In the middle of Oak Grove between its two hills there was a cut-your-own Christmas tree farm which yearly drew hundreds of families to Oak Grove. It was started in 1978 by later Oak Grove Mayor Bloise Zeigler, who operated the farm through 2009. Zeigler grew the official Alabama state Christmas tree, which was displayed at the Alabama Governor's Mansion in 2004.^[5] The Christmas tree farm was closed in 2010 and donated by the former Mayor to the Town of Oak Grove as a community garden named "Comet Grove".
