I'll be bringing my Viton check valves, I don't have many sets in stock, just re-ordered today but I won't get the new order in time for the trip. But, anyone at the event can buy at the hookup price of $10 for a set of 4 and I'll ship them out.
I'll be giving one set for raffling off as well
.
I'll probably be digging through my stuff and bringing a few neat things for sale with me.
