Because I was driving a Tank!
This was an Xmas gift from my wife. I really thought it was a wacky gift but wow we ended up having a great time!
There are several places like this across the USA, and I am sure in England and other countries. We visited driveatank.com and they really treated us well and we had a great time! If you have any interest in this kind of stuff I highly recommend you pay them or a place like this a visit! You will *tank* me later!
I know another popular thing we have locally is to play with big construction vehicles like back hoes, dump trucks, cranes etc. I guess the adult version of playing with Tonka trucks.
This video starts with a few short clips from our personal experience and because you can't really carry cameras (prehaps think of bringing a head mounted GoPro, and they do have a mount on the tank) I added some of Drive A Tank's promotional videos so you could see more of the driving course.
