So I went there. Well stocked, prices were a bit high but I guess par for this area. I got a sort of unfriendly vibe though: courteous but somewhat cold, not interested in chatting at all. I'm sure it's a decent place but not my kind of local. There was a sign "help wanted" so I asked. I don't really need the job, just thought I could share some experience and meet some people. I was told "go to the web site" even though I was right there and the owner was right there also! Weird.
Anyway I ended up finding a place in Sebastian where the owner and his son actually were friendly and spent a good 30 mins talking recipes. Not anywhere near as well stocked, but they said they could order me what I wanted so that's my new local home brew store.
I'm not casting aspersions, just my one experience. I'm sure Brock's is a fine homebrew store.
