3? lol.
Damn, you love to exaggerate. The list is here - a bunch of those are not bottled, and many had very limited distribution (if any).

We get it. You own or have tried so many beers that you can't be bothered to attend an event unless it has a substantial food pairing or features beers that you can't get elsewhere. But what you don't realize is that sometimes festivals are more than simply what beer is offered. Sometimes it's about being able to try different beers all in one place...or it's about the event atmosphere itself. I know being a jaded beer drinker with thousands of ticks under his belt kind of kills the magic for you, but sometimes it's not about the hunt, or the tick, or the .rar, or the walez. I know you don't love the crowds (neither do I) so that makes sense - but your estimation of what was a shelf beer is a bit off.
axeman said he's flying into town, so we can assume that many of the beers at the barleywine fest are not available to him (since many on the list aren't distributed at all.)
All that said, the crowds may make the event not worth it. It's up to you to decide - I just recommend getting there early and sitting near the bar.
