I use Noble for grains and the odd dry yeast, mostly because they are the only game in town.
My only issue is that I am a serve yourself kind of guy, so when I walk in and just start measuring out grain, I often get the "what do you think you are doing" look.
I mean, as far as I know, it is self serve, if the workers want to measure it out for me, have at it, but I sometimes will go in with what I need for a recipe, and call an audible while there. Recipe calls for Crystal 30, and they have 20 and 40, or maybe instead of regular pale malt, I will go for whatever is being offered from Horton Ridge. Not sure if it makes much of a difference in the long run, but at least using Horton's stuff, it is like using local ingredients.
