It's fun to see the stats but I think that Dicks is one of those situations where "you don't know until you know." I think this is easily the best venue they play for a number of reasons, some of which haven't been mentioned. One of those is that it's an outdoor venue where it is dark as set 1 begins; this is definitely a rarity, as most of the outdoor sheds are summer spots and Kuroda doesn't really get going til set 2 because its too light through set 1. Another reason this venue is so good is the incredible sound. I'm not an acoustics nerd but the sound in there is definitely superb; maybe it's because of the altitude, or the shape of the bowl?
The weather every time I've been has been fantastic, and that factors in too. I don't think it's just the fans that love Dicks, the band clearly does as well, or they wouldn't return every year. I imagine the sound, the weather, and the vibe all have something to do with this, added to the fact that they feel a strong connection to CO.

This may get me a .net flogging, but I also want to say another thing about the statistical approach to this post - I don't think we are in an era where it is valuable to analyze Phish shows via data sets based on reviews. I think there is a ton of attendance bias with the way we look at shows now, and far fewer "no-doubter" shows than there were in the late 90's (although one of the few "no-doubters" of 3.0, and possilby the best all around show of 3.0, was FYF 8.31.12, @Dicks). I think many of us go to be with our friends and have fun but would probably agree that the band isn't as regularly/reliably on fire as they used to be. Every time they go on tour I listen to each show, and attend a few. I generally read up on what people thought and there is always, for everyone who was there and says it was sick (great vibes, great energy in the room), at least an equal number of stream viewers who thought it was weak. This is a function of the era to me, and it renders the statistics that this post is based on somewhat meaningless.
Thanks for disagreeing politely and thoughtfully if you decide to!
