ohhh Mary - with the miles you're putting on, you are gonna LOVE a road bike. And nah, my first "get back into riding" bike was the Trek Navigator 200. I still have her and she sure looks purty sitting there! I'll use her this winter when the weather gets dicey but other than that, she just sits there! Bikes are like dogs - they have unconditional love! Your Lil Navigator that Could will always be there for you!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
