I have spent quite a bit of time on the western portions of the Burnt Bridge Creek Trail lately and I noticed there are several grapes growing wild there, with grapes on them. Some of them are really big, reaching 35+ feet into the trees. I am guessing they were planted by birds. I was able to pick a couple of clusters and they are tasty. I am tempted to try planting seeds and/or taking a few cuttings. Any fruiting plant which receives no care yet thrives and produces abundant fruit is OK in my book.
