I'm just signing up for it now, though I don't know anyone else riding in it either.
I'm not too worried about the hills, although there's not much opportunity for that here in Houston. I am a little concerned about finding a place to stay overnight, however. All of the State Park's campsites are full (big surprise there ) and booked for the weekend, though I was hoping I could just wander in and find a friendly group willing to accommodate an additional camper.
