I've been driving for awhile now. only once in a blue moon will i get a ride to NYC or Boston. I always have a $20 bill hidden somewhere in that rare chance i get one of these rides. There are no tolls in CT, but I've had a couple rides recently out of state and starting thinking about EZpass. should i even bother? I i get it and add money to it, do the funds have an expiration date if i don't use it for a few months ?
