I deleted my original post on this topic as I have never attended a PB conference and did not feel my input was relevant. But now since Sunil is gathering data, here goes.
I did not attend due to health (heart can't decide whether it wants to stop or beat too fast).
We have a little .5 +/- acre watertable pond with aeration already so not really interested in buying vendor products or learning about managing ponds different than my own. Anything I learned would however be a plus. Tough job for the organizers to come up with speakers and topics that are relevant to most everybody.
My main reason for attending would have been to meet other forum members, you know, put names to faces and lie to each other about the size fish in our ponds.

So, for me, expensive for what I'm looking to get out of it. I don't really need the luxury.
To be honest, the GTG Snrub is planning fits better with my goals. I will do my best to attend that. I might only spend a couple three hours at Snrub's before I need to head back to the motel but, it will still be well worth the trip to meet some of you jokers! It might take me a couple days to get there and a couple days to get home but I can always try to find interesting sites on my journey like "Worlds largest ball of string," biggest ear of corn, two headed piglet, etc. at gas stations and truck stops along the way to keep me entertained!
