I am disabled and walk with a walker, but to do shopping like we use to do or to look in antic stores we will get a wheel chair because I can't handle the pain. If I were you I would get a wheel chair and let your friends keep care of you, as they will enjoy there time more because you won't slow them down. I don't get to buy things any more, but to be able to do things would be great, so we are trying to save money so we can get a wheel chair from good will. can you imagin having to try in save $20.00. God bless. Penny
