You are right about the dogs. Friends of ours just had their dog picked off the ground by a much larger dog on a lease. The person was walking three dogs and could not handle them all.
For some odd reason when people go into weekend parks they leave a lot of their good manners behind at their S&B house. Must be the attitude that they will never meet these people again, and they are paying to enjoy themselves so full speed ahead.
I think you will find snowbirding completely different. In these parks it is much more community related. All the things you were looking for in the beginning you should find. Come join the rest of us snow birds, we would love to have you as a member.
