I voted that I consume cask beer regularly because whenever I encounter it, I'll almost always have a cask beer over other offerings. There are some really good brewpubs in the Twin Cities that offer cask beer regularly. When I lived in Nashville (1997-2005), I would regularly get Boscos or Blackstone cask beer when it was available.
As a side note, cask beer doesn't impart a woody flavor -- it's not like the beer is barrel aged. It's typically very fresh beer that's naturally carbonated in the cask and then hand pulled via a beer engine. Cask beer is typically served in the mid-50s and has lower carbonation. Also, some beer engines are equipped with "sparklers" which is a fitting that goes on the tip of the faucet that infuses the beer with atmosphere as its drawn, thus creating that neat cascading bubble effect.
It's only 7:40 a.m. and now I'm wanting a cask beer.
