Roll the tollway--every day!
Don't mess with Texas.
From Commute by Bike:
Commuting By Bike on Austin's Tollways
"Chuck e-mailed the Texas DOT trying to find out if riding a bicycle on the tollways in Austin was legal. The response he got was that it was legal … but they hoped he wouldn’t do it. He carries a copy of the e-mail reply with him and has had occasion to show it to authorities who have tried to stop him."
Hey Chicagoland Bicycle Federation, did you say you were looking for some more ideas after Roll the Tollway?
(Psst: Bike the Drive registration is open--go sign up! Or consider volunteering!)
