Yesterday I decided to practice with the drone.  Unsurprisingly, it was a little complicated at first, but now I know the basics.  The drone has a pretty cool feature which allows it to fly back to the spot it took off from and land all on its own.  It has sensors which enable it to go up, over, and around any obstacles that are in its way. In the past when I have told it to come home, it has worked fine, but yesterday it ran straight into the top of a tree.  A 200 foot tall tree.  As soon as we realized what happened, Dad and I tracked the signal all the way to the right tree.  Luckily this tree was in the yard of a very nice local, who had a friend that was a professional at climbing trees.  The next morning, with the persuasion of some reward money, his friend spent three hours climbing the tree and safely retrieved the drone for us.  With only a few scratches, the drone is fine!
