Upcoming research trip

I'm planning my first family history research trip for next month. I'll travel to Memphis, Decaturville, Nashville, and Lewisburg, Tennessee.  I have a lead that there are some Decatur County court documents at a library in Memphis. I'll check that, then proceed to Decatur County to meet with both a Yarbro and a Crawley cousin, on to Nashville to poke around the state archives, and then to Lewisburg to try to substantiate that Frederick Fisher was the father of Michael Fisher. It should be fun!
