1981, panhandle of Florida for a week. As a fantastic carryover from the 70s my high school offered a week in March/April where regular classes were suspended and the students could take an intensive version of a class that wasn't offered in the regular curriculum. Usually poetry, weather science, etc. In addition, some trips were offered and one was a "bike camping" trip. We had meetings at night on what equipment we needed, how to set up camp, proper riding form and cadence on rollers (since there was snow on the ground), etc.
About 25 students went on the trip and we went from Tallahassee through Panama City to Pensacola and back averaging 50 miles per day. I even experienced my first right hook, going over the hood of the car. Fortunately, just a scraped back and shoulder. Anyone who says FL is flat should ride the northern panhandle where you go up and down the same 200 foot hill all day. I still use the Cannondale panniers that I bought for the trip and it was a great introduction leading to many tours down the road.
