I have been attending such shows since 1998, and have found them to be quite enjoyable. You will need to be prepared to answer many, many questions -- probably repeatedly during the show. Some of us who frequently show our rigs at such gatherings have scenarios that we establish through decorations that we place in and around the coach. My usual scenario includes The Long, Long Trailer
playing in my video player, my PowerPoint show of the 1999 Wagon Wheels Caravan and International Rally in Dayton, and a display of literature pertaining to my vehicle(s).
I have made plans to attend such a cruise-in later this fall with my 1975 Cadillac Eldorado Convertible and 1964
Once you try attending one of these events, you may find yourself making plans to attend on a regular basis.
