Here's a nerdy hobby that I never got into, but probably would have liked: Shortwave Radio. While I'm not too keen on listening to the regular radio these days, the thought of hearing a broadcast that is happening from the other side of the earth (and is not being broadcast via the internet) is pretty neat. The fact that this technology has been around for years is even more intriguing for me. I may have to look at how much these things cost and pick one up. It's never too late to pick up a new hobby!
