Road riding for me! If I had to choose only one bike, I'd pick the road bike. That's not to say I don't like to mountain bike. I do, but the road is my first love. The speed you can attain......... it's just awesome! If I went fast like that on a mountain bike, off-road, I wouldn't be around to talk about it.
For me, the mountain bike is more work. I'm just not as good on it, nor as skilled, as I would need to be to really be able to totally enjoy it. I have to work hard just to stay upright sometimes. Not that that's a bad thing....... challenge and learning new skills is fun in it's own way, and getting out on the trails and away from cars is also great...... still, my road bike is my first choice.
Just give me a bike and let me ride. I'll be happy..........
Time is a companion that goes with us on a journey. It reminds us to cherish each moment, because it will never come again. What we leave behind is not as important as how we have lived." Captain Jean Luc Picard
