I'm signed up for the 70 mile route.
As for doing the 20, don't be concerned, how bored can you get on 20 miles? Now 70... I might get bored
Atleast I've never driven it either, so it'll be completely new
Eh, whatever, I'll try it once to support cycling in Houston. The "nice country asphalt" has a way of being viscious sometimes also. I don't usually need much support at stops... I mean, I love the oreos and all, but could get along with out them.
