Glad you had a nice ride. Chappell Hill is one of my favorite places to ride. I've ridden to Washington-on-the-Brazos and back countless times.
I was signed up for the ride (60+) but work stepped in at the last minute and kept me from riding at all this weekend.

So much for the $20 extra for the T-shirt I bought. At least I didn't pay in advance for the lunch.
Both Saturday and Sunday were days not to miss (and of course, I did). A buddy rode the gran fondo ride out of Montgomery and said it was a great ride.
I've ridden the Rolling Hills Challenge a couple of times - both in the mid 1990's in it's early years. It's on the calendar again this year. Fingers crossed that I make it.
