We hear people using the MURS Frequencies all the time at ski areas that I work at. Families, groups, etc., use that radio service quite a bit.
We have a scanner at several ski patrol offices (base), which has those frequencies programmed into it a long with; FRS, GMRS, Amateur radio 146.520 and 446.000 calling frequencies, plus the 146.580 North America Adventure Frequency. Comes in handy at times.
