What timing! Was disappointed last week when my NJ EZ-Pass didn't work in FL.

Have had it for maybe 10 years and used it up and down the East coast, was surprised it didn't work in FL. So now I will need to have BOTH transponders for FL and East coast as I plan to drive to NJ/NY once a year. Anyone who has driven through those tolls, knows the high COST especially on the NJ Turnpike and crossing bridges (almost $50 roundtrip from NJ to MD). Boo hoo, but on the bright side, don't have any tolls nor meters to worry about in The Villages.....another plus for living in TV.
