Patrick -
So that I understand you - you were on the top of Eisenhower, off the trail on the alpine tundra, and another hiker spoke to you about it. Are you venting because 1) You weren't off the trail, 2) You think it's inappropriate for another hiker to call being off trail to your attention 3) You felt the other hiker was rude in the way he/she brought this to your attention or 4) none of the above.
I was out and about myself over the weekend, mostly above treeline and there were LOTS of people as you might expect, people were using the summits much the same way they do in parks - lounging everywhere, sprawled on blankets, etc. Kinda makes you wince to see it, especially when you know how long it takes a diapensia to recover from one boot print, but ... fortunately, it's been a very wet spring and maybe this will help the plants and flowers recover more quickly (as in 30 years, not 50)
