Wyoming or Utah, Camera stores?!

[Shor]

Hi,
I was going to pick up a lens in Las Vegas, but never found the time. Now I am in Jackson, Wyoming and will probably head to Park City, Utah next week.
Does anyone know any good camera stores in either of these places? Or nearby? We have a rental car so some detours aren't a big deal.

I am looking for a Canon L-series lens, so many stores doesn't seem to have those.. I tried Best Buy in Salt Lake City, but they said they didn't carry L-series lenses..

Can anyone help? =)
