It is great, you get to meet many new friends that you keep in touch with over the year. At times you plan a rendezvous and have a wonderful get together and split up again to head off to individual destinations.

Most of the campgrounds that cater to Snowbirds (Arizona, Texas, Mexico, Florida) have ample programs and facilities that encourage social function.
