Lived in SF for 5 years and Labor Day weekend was the ONLY weekend of the year when you were absolutely, 100% guaranteed a nice weather weekend to make outdoor plans. Not sure it's that way in Palo Alto, but trj is correct...there are a lot of other interesting outdoor things to do in the Bay Area on a nice weekend.
Was at the Iowa game last night and very impressed with the Iowa student section: full and loud! No difference between last night and a BTen night game that way. I had no idea it was a sell-out and was pleasantly surprised. Barta should make it a priority to get Iowa's first games (usually vs. lower tier teams) be at night, if this is any indication.
