I should do it too, gym is good but just not enough. Fortunately I can ride my GG from the garage and this fall rode for eight consecutive weeks, felt great. I have a county park with dedicated mtn. bike trails near my house, races are held there too. Problem is I have an old Diamond Back Accent with no suspension. Good components but really stiff, even on the road. I got my kids some cheap bikes for Xmas, and looked at some cool new mtn bikes with disc brakes, etc. $800 for a cheap one with just a fork.
Another $$ toy. What do I have to spend for a good modern bike, or how much to bring my old one up to spec with a fork and is it worth it?
