I decided to go camping tomorrow night.  To prepare, we needed to get some supplies.  We took our sleeping bags from the closet, and put them in the trunk of the car.  We packed a bag with food; snacks like pretzels, canned beans and corn, sandwiches, fruit and some water.   We carried blankets, flashlights, hats and gloves to the car, and packed a separate bag with clothes and extra shoes.  We made sure that we had a map that would direct us to the campsite, and extra batteries for our flashlights.  We were only staying one night, but had to make sure we were prepared for cold weather and had enough food.  When the car was packed, we went to the gas station to put extra gas in our car to make sure we would have enough to get to and from the campsite the next day.  We would sleep that night, and tomorrow morning would pack our pillows, tooth brushes and toothpaste, get dressed and get in the car to drive to the campsite. 
Question: How long did it take to plan the trip?
one evening
