I thought about it, and wondered how I could feel that 11 people in a small area isn't crowded. In my two or three trips to Yellowstone , you can't help but notice the crowds, especially around Old Faithful. Gazillions of people all creaning to get the perfect video of Old Faithful erupting, surely to bore the heck out of their close friends and relatives back home. After a view or two of the video's they will never be watched again, I guarantee it. Bicycling or hiking to a crowded national park area really changes your perspective, if you aren't convinced that we take overcrowding for granted.
Tourists flock and often look like sheep without a sheppard.
When I bicycle on long tours the culture shock is so great that I usually high tail it to the nearest exit and go on my way. I guess I like to selfishly have nature to myself. Or perhaps we'll do quotas like we ration water when there's a shortage. Perhaps a look at hunting will tell us a bit about the future. Many big game hunters must now go to parks and reserves and shell out big bucks to take their precious kill.
