Memorial day is still five weeks away, and summer doesn't officially start for two months.
But that's not stopping folks from worrying over high gas prices already.
With gas prices above four dollars in some states, Americans are canceling spring break plans and rethinking summer vacation.
In an effort to keep tourists coming, some tourist destinations are offering gas vouchers of as much as 50 dollars to talk people out of giving up and staying home.
At Mount Rushmore, only about 37,000 people decided in March that seeing the four granite-etched presidential sculptures was worth the trip, down from about 43,000 people a year before.
It's too early to tell how much of a toll gas prices will take on the summer travel season. The jitters have come so early that AAA hasn't even put out its summer travel forecast yet.
