ROO, I like your idea of a PC gathering. I also like your Florida suggestion.
Prior to our PC we owned a small molded fiberglass travel trailer (Casita). Various owners across the country organized Rally events throughout the year. I attended several of them and always enjoyed meeting other owners. The gatherings were great learning opportunities as well as meeting new and old friends. I attended gathering with as few as 15 to as as many as 80 other units. None of these gatherings were sanctioned by the RV manufacture. Whatever organizing effort required was done by volunteer(s).
These gatherings were generally informal. They typically had limited organized events during the Rally and the attendees could take advantage of some, all, or none of these. Some events that were scheduled were morning gathering for coffee, pot luck dinners, special topic gathering (examples of those I attended: planning an Alaska trip, RV maintenance, cast iron cooking, etc. ), and group visit to a local attraction.
The cost for the gatherings was also very minimal. The most I recall paying other than campsite and food was $5.00 per campsite. This was used for name tags, morning coffee, and other minor expenses.
I attended gatherings in private, state parks, and Corps of Engineers parks. Each unit attending was responsible for making their own reservations. In the case of the private park a group rate was provided and held for anyone wanting to attend up until a certain date. For the government operated parks anyone wanting to attend were encouraged to make reservations as soon as allowed (6 months for federal, and 11 months for state).
I know a number of us snowbirds migrate to Florida for some part of the January to March time frame. This past year we ran into 5 other PC owners at campgrounds we were staying. Since these were chance meet ups I would think there were several PC owners that were dodging the snow or Florida residents that were in the “Sunshine State” at this time. If a gathering was organized with enough advance knowledge I would think several may want to attend.
Depending on others response to your posts it may be worthwhile doing a poll to determine the level of interest and location for a gathering.
