Interesting South African tree

After I was "fetched" at the airport by South Africans Antoinette and Ena (short for Magdalena), we swung by the office of SAAWE (South African Action for World Evangelization) to pick up some photocopies that had been made for our training meeting tomorrow. While waiting, I marveled at the nearby perfectly shaped tree and inquired about it's name. Our transport driver Antoinette burst into laughter then composed herself enough to tell me that it was a cellular phone tower! Later, I saw a few more of those perfectly shaped trees.
