too much rain

I have a bad back, 2 operations and the rain and snow kill my back. well we have had weather in the low 30s and then back to 60s for the past month, and it has been a wet past month. Me and my kids like to go for walks on trails that take you way deep in the woods but I cant do it when its raining, cold or snow, so what to do? Its about the only thing that gets me and the kids out cept for we go to the movies once a week, and if not that we go play pool. in the summer we go to the swimming pool and then on weekends the drive ins, plus our walks, so we get out more. my children are a 19 yr old girl, 2 17 yr old girls and a 14 yr old son (yea all teens at once what fun hehehe) any way this is my first blog here so hello everyone!!!
