I don't remember any proposed changes to the antelope season dates so you should be safe using last year's info. Some of the tag amounts may change though. Unless you are actually bow hunting there are only a couple rifle hunts that are open in August and they are a few hours from Ketchum.
I was at the BHA Hunting Film Tour last year in Ketchum is that what you are planning or are you bringing in something else. Feel free to PM me if you don't want to hijack your own thread with the details.
