I think you've received some sound advice here from some people likely more experienced than I. One piece of advice i will give you is to try and look objectively at the oppurtunity. I know you have looked at it romantically and think it is always what you have "wanted" to do.

Be aware, that since you have never done it, you are only speculating on what it will be like. Chances are that it will be NOTHING like you imagine it will be. Most things aren't. I have to admit that the allure is there for me as well. Hmmmmmm, being surrounded by bikes, all day....that would be perfect! Or would it?

In high school i ran an icecream shop in the summers. It has taken nearly 20 years to learn to enjoy icecream again. I would never want that to happen with bikes. I simply love them too much.
