my mom and step-dad live out in the country. they have 8.5 acres of land (2 acres is a stock tank (pond to you northern folks). she told me she has mesquite, post oak, and other trees. i have seen a huge mesquite tree out there. i don't really know one tree from another, by looks, except for a few. i have two big pecan trees here in my yard. she told me i can have all i wanted, just to let her know and she will cut me some and bring it to me. my question is, has anyone ever used post oak?
