I'm searching for information on how to obtain the toll pass gizmos so that I don't have to stop to pay tolls every 8-10 miles while going to the Chicago Pinball Expo, MGC (through ILL), Replay FX, and maybe a few others. I live in MI, so I can't really go to the local drug store to buy one and subscribe. Looking online the instructions are for those that live in those states for subscriptions. What is the best option for using it once every 4 months or so. Is I-Pass the same thing as E-ZPass and work interchangeably, or would I have to buy/rent/subscribe to each one. Just trying to understand the concept. Those toll roads are a real pain to drive through. Or is it just better/less of a hassle to carry lots of change and singles and stop every 10 minutes to pay. Please explain/advise. Thanks!
