Man, I'm so dense sometimes. I only have a dual band in the truck (2m & 70cm), but I can use 6m on my HT. No 11m other than the CB, though.
Edited to add:
I also monitor the Colorado Connected Repeaters, which cover the whole state. From the White Rim at the White Crack Overlook C.G. I am able to open the Grand Junction repeater. It's not noise-free, but it's understandable. That repeater is 145.355. It, like most all the ColCon repeaters, is 123 Hz PL. If you want to try that, I'll be mostly monitoring those repeaters while driving over and should have a better chance of hearing you Wednesday or Thursday morning.
