What do we do?
We're staying @ a 55+ RV community that offers activities from 8:30a to about 9:30p, Mon-Fri. Saturday nights are dance night. Every other Sunday evening is a cake social & entertainment for 3$. I've gone to the local library & got a library card--books & movies. We've gone to local attractions, esp museums. Every week we have to fit in groceries & laundrymat. We go to other parks garage sales. Our park has a jam session of country music every week. Last week we visited another parks music. There's an exercise room, pool, ping pong, & 2 tables set up with puzzles in the hall. We have a pool & hot tub. I've joined horsecollar shuffleboard. Hubby has joined euchre club. We ride our bikes daily.
In other words--you can be as busy as you want. And decide how much $$ you want to spend.
