nearly every hotel and motel room, campground, and in some cases backyards for nearly north and south of the path of totality had been reserved several months, if not years, in advance. The state anticipated up to 500,000 visitors to join its 1.6 million residents. Oregon deployed six National Guard aircraft and 150 soldiers because the influx of visitors coincided with the state's fire season. Hospital staffing, and supplies of blood and antisnake bite antidote, were augmented along the totality line. Also in Oregon, there were reports of hoteliers canceling existing reservations made at the regular market rate and increasing their rate, sometimes threefold or more, for guests staying to view the eclipse. The Oregon Department of Justice (DOJ) investigated various complaints and reached settlements with affected customers of at least 10 hotels in the state. These settlements included refunds to the customers and fines paid to the DOJ. Post-eclipse traffic problems Although traffic to areas within the path of totality was somewhat spread out over the days prior to the eclipse, there were widespread traffic problems across the United States after the event ended. Michael Zeiler, an eclipse cartographer, had estimated that between 1.85 million and 7.4 million people would travel to the path of the eclipse. In Oregon, because an estimated one million people were expected to arrive, the Oregon National Guard was called in to help manage traffic in Madras along US 26 and US 97. Madras Municipal Airport received more than 400 mostly personal planes that queued for hours while waiting to leave after the eclipse. Officials in Idaho, where the totality path crossed the center of the state, began planning for the eclipse a year in advance. The state Transportation Department suspended construction projects along Interstate 15, which traverses Eastern Idaho, from August 18–22 in order to have all lanes open; their counterparts in neighboring Utah, where many were expected to travel the north via the highway from the Salt Lake City metropolitan area, did the same. On the morning of the eclipse, many drivers left before dawn, creating traffic volume along I-15 normally not seen until morning rush hour; northbound traffic on the interstate in Box Elder County north of Salt Lake City slowed to . The Idaho State Police (ISP) stationed a patrol car along I-15 every between Shelley and the Utah border. After the eclipse, traffic more than doubled along I-15 southbound,
