Dear TB,

I think the key will definitely be to find an ETC gate with red/green light and no swing gate, and I think I've seen these. Otherwise, the best method is to roll up to the rightmost gate, which is always wider than the rest, and roll through with a truck or even without. You are through before anyone has a chance to react, and in my experience no one calls ahead to the next toll gate. At the next gate, you do the same thing, or stop and they'll ask, how did you get on, and you say, They let me on at the previous gate....

cheers
