I did give OCB a quick thought, but was out of town anyway.
Frankly (and those people who know me will think this is a totally crazy thing to say) I just can't drink enough to justify the cost and hassle of going to things like Sessions or even Cask Days. Been there, done that.
I much prefer smaller focused gatherings or the more casual Brewers Backyard type things, where you don't have to wait through massive crowds or do a mission plan to figure out what you want to try.
Tap takeovers can still be fun and I probably would have gone to at least one if I had been around. It's still nice to meet some of the brewery folks and get a sense of how they like to present their products.
Brands are for cattle.
Fans are cash cows.
The herd will consume until consumed.
