I can try to throw one together tonight, but there isn't much to listen to in Wexford Co. City PD/FD and County SD/FD, thats about it (SD and FD freqs listed here on RR are correct, city PD/FD are dispatched over the county freqs). There isn't much traffic on the MPSCS as the MSP troopers here also have VHF radios in their cars and do most of their work through Central. However, if you want to listen to other areas, Grand Traverse Co. is right next door (Buckley is right on the boarder) and MUCH more active than Wexford.
As for any radios used at the show, I don't know what they're freqs. are (or what band they use for that matter), but I'm sure a little searching would find them.
