Inquiring Minds Want To Know...

What exactly do Baptists believe?
I'm pretty sure I can say this without offending anyone (right?)... there are a LOT of Baptist churches down here. I mean A LOT. There are literally 5 in a row down the street from us. Five in a row... not kind of near each other... literally next door to each other. What is the deal? Obviously I realize it is a Christian denomination. In Michigan there were a couple Baptist churches in Ann Arbor but not more than any other denomination. I looked up the churches in Asheville... and I'm not exaggerating... there are 53 Baptist churches in Asheville (there are 6 Episcopalian in case you were wondering ;). Fifty-freaking-three! I just don't understand how that can be necessary... or possible.
Seeing as two of our "elderly" neighbors have invited us to attend the one around the block (and I'm totally going to go... you know how I feel about religion!) I'm curious to know what I should expect.
