Either of your ideas with your mom and her motorhome sound good. You'd get to do the long-distance cycling you want to do, and your mom would feel less worried about you. Plus you'd have your very own support vehicle along--nice bonus!

Was it Vermont Bicycle Touring that you were researching? I took a short tour with them back in the late 80s, and it was great. Very friendly, supportive guides, well-researched routes and maps, wonderful B&Bs that we stayed at. I think that sort of thing is more expensive now (what isn't?), but worth considering if you want to tour but have no one to tour with and don't want to do it alone, at least your first time out. And don't forget to check out other touring companies. I highly recommend Womantours--took a nice tour with them in Maryland last spring, and I'm thinking of joining them on a longer one next year, either riding up along the Mississippi River or a week-long tour in southeast Alaska.
