They went to the "working volunteer" tags, then spread the word that those would be required to park in that lot: then, apparently when they saw how much all those extra hang-tags cost, they didn't hand them out if your shift wasn't starting after three or so in the afternoon (since there would be plenty of room at other times, of course) . As a result, some idiot VP apparently didn't get the memo, and started storming around telling all the cops they hired to babysit the gates that no, you've got to have that extra hang-tag no matter what. As a result, no parkee in the wide-open, empty lot at six in the morning, and no shuttles, etc. to go to the BFE lot they stuck us in as the alternate. If your shifts started at four in the afternoon, you probably had the tag and never saw the problem: if you had any of MY shifts, you were screwed. My wife got all of her "hang-tags" for all her shifts, nobody in our committee did. I'm not sure how many others got stuck in the same debacle.. In other words, the reason you saw "plenty of parking" was that they weren't letting a lot of people in there that were supposed to be there, and basically got left to their own resources...
That as a result of, and touted as the "fix for", last year's "reserved committee parking" that magically turned into "cash parking" after day 1 of the rodeo: cash talks, volunteers walk. and walk.. and walk.....
