It is off of Jefferson Pike. Take 840 (toward Knoxville) and take the Smyrna exit. Turn right and look for the sign (a few miles down). It will be a left turn to the school. It sits back off of Jefferson Pike.
All 4 of us made it back. I ended up with some pretty good road rash and a twisted elbow, but I'm ok. Had work on the bike a little after the spill but it's ok too. We ended up with almost 31 miles. Had a lot of fun.
