BBQ in Maryland

So I don't know if The Corner Stable has gone downhill or if I just wasn't educated enough as to BBQ. But the last time I went in there, the ribs were clearly boiled, and while the sauce itself was tasty, the ribs themselves weren't bad, but extremely bland.

Now I'm looking for a new BBQ place. I live in the "Greater Baltimore Area".

I've actually got a few questions about a couple places that are nearby and convenient.

Kloby's Backyard BBQ
Famous Dave's
Andy Nelson's BBQ
Archie's BBQ

Also looking for any great hole-in-the-wall places that might be below notice.

Don't bother mentioning The Canopy. I went in there once, it was filthy and the pit was clearly long out of use. Never again.

Thanks in advance.
