@Tls5150 - generally speaking, rallies are all about like-minded people (RVers) getting together to share, learn, eat, help and have fun.
Activities often include:
- Meet and greet
- Campfires
- Potluck meals
- Sponsored (manufacturer / vendor) meals
- Seminars (technical, lifestyle, travel etc.)
- Crafting
- Sightseeing
- Show and Tell (modifications, fixes etc.)
- Helping each other out on RV matters
- Games
- Travel planning, travel sharing etc.
They can be a lot of fun and quite insightful.
