Since some of you guys also plan to visit and fish in Yellowstone National Park this summer, here's what the fishing permits will cost this year:

"Anglers 16 years of age or older must be in possession of a valid Yellowstone National Park fishing permit to fish in the park. State fishing licenses are not valid and aren't required.
Three-day permit: $18
Seven-day permit: $25
Season-long permit: $40"
