Liz and I are certainly in that camp. Patrick too, within his time-of-year constraints.(because I'm a variety junkie)
There are tons of skiers who like Harvey limit themselves to one or a handful of areas within drive distance of home. SoCal's population of Mammoth only skiers is one of the largest subsets of that group. Harvey's radius is just tighter. The advantages of a locally restricted plan like that:
1) Low per ski day costs (season pass, daytrip or cheap lodging)
2) Short notice powder days
3) Minute detail knowledge of the ski area(s), especially valuable on powder days.
