Going to DENVER, any WHISTLE shops?

Hi friends, I’ve been learnin’ lots the last few months from all of the posts here. Thanks for the lessons. OUT here in West Texas, the only whistle you can find at a music store is a REFEREE’s whistle. We’re big on Football, I guess… Anyway, I had just started playing a couple of months, when STAN, a wonderful tutor/mentor, found me. He offered to share and now I’m gaining on it! It is so much more fun when you can share the music. I started out on one of Thom’s tweaked Clarkes and from out of the blue, I was blessed with a Copeland D that I’ve liked each day more & more. I’m taking my daughter to school in Denver this week and wondered if anyone knows a place(s) a fellow could go and at least LOOK at and/or HEAR a REAL whistle or two. We’ll be in the Cherry Creek area and also close to the Capitol bldg on Lincoln til the 28th. Any help would be appreciated… Thanks, Mike
