I just got done running the Rock and Roll marathon here in San Diego. Actually I only ran the half marathon but about 8 miles in there was a big Michigan tailgate. They had about 15 tents and about 50 - 60 people on the side of the road cheering on all of the runners wearing Michigan gear. Unfortunately I was not wearing any Michigan gear but when I yelled "Go Blue" as I ran by they were all on their feet cheering and giving high fives. It was VERY cool.
On a side note I saw about 10 people wearing Nebraska gear and about 10 people wearing Cal gear.
I saw two Sparty fans running and two Sparty fans cheering.
Other than that I saw no other college affiliation so Michigan clearly was tops. It was great to see them out in force.
