i was born in oregon so oregon,idaho, montana and wyoming are my stomping ground when i go somewhere.if you go to yellow stone make sure to plan 2 days in gardner montana right out of the n. entrance,stay at the yellow stone motel,[mom and pop place]the back patio is on the yellowstone river the view is fantastic!the elk come into town and feed everywhere. take a day and book a float trip with one of the fine outfitters there[i have my fav but not gonna drop names there all good!]the gallitine is kinda of easy float after june,but the yellowstone still has a very wild ride after june,[before june no kids after no big deal]class 2 to4 after june, yellow has a rapid named boxcar that is awsome!when you drop into it towers 25 feet above you!awsome ride!something to think about!mike.
