Iowa 80, World's Largest Truck Stop truck stop is against the convoy I think everyone should give them a call. Husband went to get a shirt printed up and they said we were told not to print anything that has to do with the convoy. All he wanted was a shirt that says "lets roll" with a big tire on it... The lady voiced that they have certain Phrases that they are not allowed to print do to the convoy..WTF Phone Number 1 563 284 6961 I bet we can shut them down once truckers hear about this.
