Hi Nancy from another Nancy-

I started out with a Jamis Quest. What is the Explorer? Hybrid?

Glad to see you are back on a bike. Nothing like cycling to loose weight!

This mileage thing gets pretty addictive. Since you live in Florida I suspect you'll be doing lots of early morning rides. Enjoy the light- a favorite time of the day for me.

Keep us posted on your progress. This is a very supportive group!
