My First Real Ride

My first real ride is coming up this Saturday. I'm just praying the weather will be good, and that I won't fall! I know it's probably inevitable, but I'm already scared to death as it is, that I think a fall would ruin me! I'm only signed up for 37 miles (I know "only" is a funny word, but I was too scared to sign up for the 45 or 70 mile), but I don't know if I can hack it. This will be a real eye opener to my dreams of being a biking star (aka-finishing the MS 150!).
