( CNN ) -- In the tense standoff between a Maine nurse and state officials , it was a surreal scene . Nurse Kaci Hickox , who recently returned to the United States after treating Ebola patients in Sierra Leone , went on a bike ride with her boyfriend Thursday -- followed by a police cruiser and a throng of journalists watching their every move . Her lawyer called the ride `` a good way to exercise her right . '' Hickox told reporters she `` just wanted to enjoy this beautiful day . '' Hours later , Gov . Paul LePage said negotiations with Hickox over where she could go had failed , adding that he would `` exercise the full extent of his authority allowable by law '' to keep her away from public places . `` I do n't want her within three feet of anybody , '' LePage told CNN affiliate WCSH . `` Right now , she can come out of the house if she wants , but we ca n't protect her when she does that . The reason there 's a police car there when she does that is to protect her more than anybody . 'Cause the last thing I want is for her to get hurt , '' he said . `` But at the same token , her behavior is really riling a lot of people up , and I can only do what I can do . And we 're trying to protect her , but she 's not acting as smart as she probably should . '' The state has made it clear it 's going to do something . But what ? `` The first thing the governor has to do , which he has not yet done , is get a court order which requires her to stay in quarantine , '' CNN senior legal analyst Jeffrey Toobin said . `` There is no court order now . She 's not violating anything by taking a bike ride or leaving her house . '' There 's no guarantee the governor will be able to get a court order , Toobin said , `` because , according to the science , she is not in a communicable situation . '' It 's unclear what the exact sticking point has been in negotiations between the state and the nurse . At first , Maine officials said they wanted Hickox to remain at home for 21 days -- the deadly virus ' incubation period . Since then , they 've said they want Hickox -- who has twice tested negative for Ebola and says she feels healthy -- to avoid public places such as stores during that time . She 's about halfway there ; the incubation period , in her case , is set to end the second week in November . `` I 'm just asking her to be reasonable , '' LePage told WCSH . `` Let 's get to November 10 , and then you can do whatever you would like . '' Attorney : Nurse was making a point with bike ride . Hickox has said it 's state officials who are n't being reasonable . She contends the U.S. Constitution and science are on her side . `` I 'm fighting for something much more than myself , '' she said Wednesday after emerging from the home where she had been staying . `` There are so many aid workers coming back . It scares me to think how they 're going to be treated and how they 're going to feel . '' Hickox has said she 's willing to compromise with the state , and that she 's open to travel restrictions barring her from public transportation and limiting her to Fort Kent , a town of 4,000 on the Canadian border . `` So I think there are things that , I know , work , '' she said . `` And I know all aid workers are willing to do those things . But I 'm not willing to stand here and let my civil rights be violated when it 's not science-based . '' One of her attorneys , Norm Siegel , told CNN that the couple went for the bike ride to make a point : She could be out in public `` without freaking everyone out . '' `` You can take a bike ride , be in the public and not actually interact with people , '' Siegel said . `` We thought this was a good way to exercise her right . We did n't want anyone in the town to be scared , even though the fear is based in misinformation . '' What could be next ? When she returned from a month working with Doctors Without Borders in Sierra Leone last week , Hickox had a temperature at an airport in Newark , New Jersey , officials said . She was put into an isolation tent .
Wars in Europe over land have failed , she says . Kaci Hickox and her boyfriend leave a Fort Lauderdale home on foot , arriving about an hour later . Hickox says science and U.S. Constitution on her side .
