How did the Vets get shafted with a midweek holiday? You can’t even go out and party with your old Army buddies since you have to get up early for work the next day. At least you can take that Wednesday off and head to any National Park without paying an entrance fee. This is the last “fee free” day of the year for National Parks. A lot of state parks are also waving day use fees, and some of them are even open for free camping that night.
