That’s an excellent introduction to Glacier. Thanks for posting it. And it has convinced me that I probably won’t be backpacking there. The level of advanced planning, combined with the need for a rigid campsite and hiking schedule is not attrative to me. I do backpack where reservations are required and sometimes hard to get. But the idea of always selecting exactly where you will camp each night loses some of the appeal of hitting the trail for me.
I have no doubt that these regulations (like those in Yellowstone) are designed both to control traffic and to decrease bear interactions, and I approve of them. But one of the great joys of backpacking, for me, is looking up a drainage and deciding to check it out. Or seeing a lake I hadn’t noticed before and deciding to spend a day to camp there.
