Yellowstone: what's the big deal about it?

Reminds me of a Yogi Berra quote....."People don't go there anymore, it's too crowded"... I went there in late September a few years ago to avoid the crowds, there were still crowds!!! I can't imagine being there in the summer. Ya know, after a few days, a bison is just a cow, get back in your car !!!! !!! Traffic back ups when a squirrel runs across the road it seems. I guess those people had never seen a animal before. There are just as nice ,scenery wise, places to visit without the enormous crowds. I count Yellowstone as one of my biggest RV disappointments. You couldn't pay me to stay at Fishing Bridge again.....I will not return!!!.Just my 2 cents worth...I've been wanting to vent this for a few years.....Not my cup of tea, but you may enjoy it.....
