One of my favorite Brown Ales is Moose Drool from Big Sky Brewery. I can't get it in NY but had it once. Then I found a recipe to brew it, and it is FANTASTIC!
I also like Dog Fish India Brown a lot! Another good one that is commercially available sometimes in California is Tasty McDole's Janet's Brown. Again, I have had a homebrew version of it that was GREAT!
Moose Drool is a pretty common beer here in DFW. It is a great brown!
