Don't make any special trips on my account. I was just geeking on a topic I once knew a fair lot about.
You may have noticed that I don't really need much of an excuse to head off down to the waterfront. Geek away, I like learning new stuff from interesting people.

When I was on active duty in the Marine Corps, I was a tracked vehicle mechanic. Along the way I became the crew chief of a recovery vehicle, and I had to learn about rigging to use the crane properly. I discovered that quite a lot had been written about it (both in the military technical manuals and beyond), and being a True Geek I buried myself in the literature and applied the knowledge in a bunch of practical application exercises. If I hadn't been quite so determined to study physics after I left active duty, I imagine I could have become a crane operator in civilian life.
The practical knowledge of rigging was very helpful when I was taking first semester mechanics class. All that stuff about tension in wires really meant something to me.
You have a massless, inextensible string....... Yeah right.
Actually, pretty high on the list of things I'd like to try one day, if the opportunity ever presents itself, is driving a tracked vehicle. Is it a)very difficult and b)as fun as it looks?

It's not especially difficult. All the ones I've ever driven had a steering wheel and the standard arrangement of pedals for throttle and brake. So it's like driving a very large, very heavy, very powerful car. It can be great fun, once you're out in an open area on a good trail. I learned things (like how to estimate the hardness of terrain, how to take a slope, and how to know when it's time to back up rather than try going any further) that have had application in driving other vehicles too.
The thing you really need to keep in mind is that you've got vast momentum. Being a physicist will help you with that. Even moving slowly, you have more momentum than you have in your car at highway speed.
and how to know when it's time to back up rather than try going any further
Yes, I've done a little offroading in the past. This is an important thing to learn!
