Ha! Sounds like the Freedom Valley Worship Cult didn't get the memo that the 60s are over--I imagine most of these people not as hell-raising crazy folks, and more like accountants and exectutive managers letting loose the one time a year their wives let them roam free for more than an 8 hour period.
I didn't notice any. We usually hole up in the abode and wait for it to be over. We did venture out and tour the battlefield on Saturday though. No preachers roaming the fields that I noticed. :) Is that an annual thing? Do they take up residence in the Square during Bike Week?
