My daughter was reading this book...
when she came across Jefferson and his cheese!
It always amazes me to read American History and find so much of it linked to our Baptist Forefathers.
Here are a couple of links with more information on John Leland and the Jefferson Cheese.

There are more books like the one above on Evangelist Ted Alexander's Website.
