What hobbies do you have?

The purpose of this thread is to show what your hobbies are (including RC), and some short info on that hobby.

Here are mine:

RC - Brushless emaxx ($2500), Tmaxx (stock, $400), mini-t (stock). Don't really need to explain much here.

Metallurgy - I spend a lot of time researching the properties of metals. Have not really spent any money on this hobby (except maybe books), but I have spent a ton of hours reading up on my metals.

Piano - I've got a $35,000 grand piano, $12000 yamaha upright, a $8000 kohler & Cambell upright, and a $1250 yamah p-140 keyboard. I play at least two hours a day.

CAD - Still new to this, and all I own is solidworks. But it is a hobby in process. Only thing yet i've spent on in CAD is the solidworks programs and custom designed savage 3speed transmission to Emaxx chassis mounts via emachineshop.

Money - I'm a avid money collector. I mostley have old U.S paper bills, and some coins. Over $2000 invested in these bad boys. And now the collection is worth more than $5000. My neatest piece is a 1928 $20 gold certificate bill with George Washington on it.

Airsoft - Sorta a dead hobby now, but I have an AK-47 AEG ($400), a WA Gas machine gun ($400), MP5k AEG ($450), and WA .45 ($600).
