blkrob, being lucky enough to have met both Al and Mark (and the Mrs!), I can say that you spent time with some of the nicest people I know. And it shows here in the community. IMO, a very large part is because Al sets the tone. He gathers wonderful people around himself to help with this online community, and set the standard for warmth and cheer. All of which I know you got to see first hand at his home in reflected in his family. And Mark - of course - gets major nice guy points himself.
And what about those fish, huh? I understand completely your thoughts about never going back to a pet shop! After seeing those fish, you'd be hard pressed to find a retail establishment that compared (though it's sounding like Houston Aquarium Warehouse could be the exception!).
I'm glad you had that wonderful experience. And thanks for sharing.
