I think for at least some, how close you are is kind of nebulous. I live up in the foothills of the San Juans, and so work is a 40 minutes commute- nothing is close. But how close am I to a ski area? Depends on what defines as a ski area. I can ski my own property, for example, we average about 150" and tend to get a 36-60" base each winter.
Next level up would be snowmobile assisted skiing, I can run my snowmobile out the driveway and up to the ridgeline above me, I have about 1200 vert there on Forest Service land. Honestly I am typically just running the snowmobile up there instead of skiing.
To get to life service that isn't me, I would have to go out to Durango, Chapman Hill is in town with a rope tow and is about 30 minutes away, 600 ish vert (1 run).
Next level up is lift service, closest is Hesperus at about 50 minutes away. Hesperus is a tiny throwback ski area on ~150 acres, 800 vert on a single double chair.
Next up is Purgatory, an hour and 15 minutes.
Wolf Creek is an hour and 30.
Silverton is 2.
Telluride is 3.
Taos, Monarch and CB are 4.5
Aspen is 6, I guess Breck Vail Summit is about that if I cared.
Farthest we have road tripped so far was Powder Mountain in Utah, which is 8. Took us more like 12 rolling a motorhome on some serious glare ice in SW Utah.
I think some of this is cultural. I grew up in Colorado Springs, which is actually farther away from skiing than it appears. Compared to Denver, it takes 1 1/2 hours just to get to I-70 heading up Mt Vernon Canyon. Even before I-70 traffic suckage, this has you approaching 3 hours each way. You do get a back way to Breck at about 2:15, however. Aside from I70, your only other day skiing option is Monarch. So, I got used to LONG ski days and an hourish to ski great places is now simple by comparison.
