In the Wheatridge/Arvada area near the I-70 interchange, I recently spotted a box-style bus labeled "Mountain States Ambulance". I don't believe I've ever seen them before, it sounds like they may be new in town. I recall spotting a single radio antenna (the smaller 700/800 MHz type). Anyone know what type of radios they might be using? (i.e. DMR, Analog conventional, something else?)
