re: What hobbies do you do by yourself?

I fly a high end drone FPV(First person view). It's awesome. You actually feel as though you are in the drone while it's up in the air and you just go whatever direction you want to and see whatever. You wear goggles and see what the drone's camera sees. I also have a model railroad that I work on in the winter. I also work on side by sides and ATV'S for people. I'm retired and I really like working on these things.
