Putnam County is enacting a temporary gas tax break.  County Executive MaryEllen Odell signed a law limiting the 4-percent county gas tax to the first $2 per gallon, regardless of how high gas prices rise.  The break is in place from now through the end of the calendar year. As Summer travel season begins, Odell says the local government wanted to make sure that drivers are receiving the gas tax break they deserve.  The consumer affairs department will canvas all gas stations and track their pricing.  She believes most gas stations will do the right thing, but will take steps to ensure that they aren't price gouging drivers.  She called the cost of gas these days highway robbery, noting that it’s taking an unprecedented toll on family budgets.
