Yeah I also noticed there were a lot of hardcore roadies speeding by me. Most of them usually ended up veering into the other lane in front of cars. And most of them never announce, which has always been a pet peeve of mine.
I agree about the poor markings toward the end. Luckily I was following a group when we reached Post Oak, because I stayed with them and cross the street left, instead of turning right like a lot did. But the cop told us which way to go. Then at the very end near the finish line there was no arrow telling us to go left.
The rest was pretty good though.
Bluebonnet Express has some hills, too. Anyone else going? I'm going alone :sadface
