My fondest bicycle vacations have been PA “Sojourns” with unforgettable adventures – these were multi-day trips, such as 2016, 2017 and 2018 to enjoy the scenery and history of PA. Some trips were with a friend, other trips were with the other 300 riders as friends. See
https://www.railstotrails.org/experience-trails/sojourns/ We heard interesting talks; toured historic sites, and camped nightly. One initial night was inside the Battleship New Jersey Museum & Memorial, and then next morning across the Ben Franklin Bridge through Philly. We bicycled to museums galore. We camped (thankfully only once) inside a gym (the local school superintendent opened the gym for us because of intense rain). We had supply trucks ( catered 3 meals/day and carrying camp gear), and toured with a 20-stall shower truck for daily showers. Part of one trip was one-way steam train ending in Steamtown National Historic SIte, in downtown Scranton (bicycles transported by truck). I highly recommend on-going Rails-to-Trails adventures.
