Glad your first was a success!
We started from Waller for our first back in 2014 as well - didn't think we could do the 100 yet. But I've done it every time since. Though they keep changing the starting point lol. Weather is the biggest factor in whether or not the weekend sucks balls or not. Thankfully every year I've done it the weather has cooperated - except some wind sometimes.

I'm hoping to get back into it next year, because I'd love to see the new route to College Station and riding into the stadium seems like it'd be cool. It seemed a little anti-climactic though from a lot of the video I saw where there really wasn't anyone in the stands cheering. Should have moved all the people that lined the streets at the finish line in Austin to there!
