Yarns from Yellowstone

Last week I went to Yellowstone with Mark and Dan, two of my older brothers. We caught 500 fish altogether and saw 40 moose, 300 bald eagles, and 4 different packs of wolves. A buffalo, who was walking down the middle of the road stopped to talk to Mark, so, Mark rolled down his window and they discussed the chemical makeup of mountain grasses. We also stopped to examine the two pies deposited exactly on the yellow line about two and four miles from where we stopped to talk to the buffalo. They were definitely his. The elk herd was near 1000 with baby elk walking in a single line along the road so that the 32 buses could stop and admire. I counted 500 pairs of burmuda shorts and at least 150 men wearing black knee socks with their shorts. Yel-owl-stone is what the early explorers called the place because of a certain yelling noise by an owl species who made their nests among the stone formations. But somebody misheard and thought it was yellow-stone. We didn't see any owls but we did see a pelican with a 5 pound mosquito on its back. Old Faithful was spewing coins and the mudpots smelled like pizza. Your job is to find the one sentence in this yarn that is true.
