My wife and I take our RZR to Brimstone OHV park in Huntsville, TN several times a year. I always have to slow down to check this tree out. It has a straight trunk that goes for ever with no branches. I don't know what it is because I don't have any trees like that on my land but it always gets my attention. Can you guys tell me what it is from this picture. BTW, my wife is 6' tall.
