Free time was at a minimum in recent years, but Pete loved being outdoors, esp. in the fall.He was a member of Summertown United Methodist Church since he was very young. However once moving to our home in Nolensville he was in regular attendance at Brentwood Baptist Church where he attended the Don Caldwell Bible study on Sundays and volunteered as part of the usher team, Room-in-the-Inn, and wherever he felt he could contribute. Besides the friends he made there over the years, he loved attending church services whenever possible, often saying how he enjoyed the Sunday sermons. Even while working out of state during the last half of his career he still attended when he was home, but lately due to Covid-19 he was unable to be there as he would have liked.Memorial contributions may be made to the charity of your choice; Pete always tried to support Second Harvest Food Bank of Middle Tennessee food.drives@secondharvestmidtn.org, Nashville Rescue Mission https://nashvillerescuemission.org/, and The Salvation Army location of your choice https://www.salvationarmyusa.org/.A Memorial Service is to be held at Brentwood Baptist Church, Brentwood, Tennessee on Saturday, November 28, 2020 at 3 p.m. with visitation 1 hour prior.
