I definitely plan to visit the SCV Museum, NBF's gravesite and Rose Hill Cemetery in Columbia on Thursday. I have been to all 3 but I want to go again. There are other things to do there and I have already done them. Not sure what others want to do.
I also want to and plan to go to Spring Hill. I have been there 3 times already but I love it there. I did the house tour of Rippavilla on the battle anniversary last year. There are a lot of tour options through the BOFT:
Rippavilla is a Greek Revival style mansion built by the Cheairs family in the 1850s. It is located on the Spring Hill battlefield, and was used by Confederate Gen. John Bell Hood on the morning on November 30, 1864.

For anyone who hasn't been to Spring Hill and wants to do a Rippavilla tour, I don't think there is enough time to do that on Friday morning and be back in Murfreesboro in time for the Muster kickoff.
With an early start, Columbia and Spring Hill on Thursday is doable. For me, the only issue would be which to do first. If a group of us do that, the deciding factor imo would be how many want to do a Rippavilla tour.
