do you think maybe you were already sick by the time the rogaine rolled around? sounded like a really fine event for you nonetheless!
I really enjoyed the rogaine. didn't even mind the rain all that much, but could have done without the shoe problems.
It's possible that I picked up the bug somewhere in between, but i'm certain I picked it up while travelling back from florida. Flu incubation period is 1 to 4 days. First sign was Saturday evening, 3 days post airport exposure.
