Can I hunt in the Wasatch National Forest with an any-bull elk tag in general season?
Since I don't know exactly what area you're referring to, I'm going to give you a link where you can figure that out for yourself.
Copy and paste the following link into your browser. It'll take you to page 77 of the 2010 Big Game Proclamation. There's a map there showing exactly what units you can hunt on. You can't use an any-bull tag in a spike-only unit.
