What other Hobbies or Interests Do You Have?

I was curious as to what other Hobbies or Interests do you have that also take up much of your time, energy and money or is Audio the only one for you?
Being a car enthusiast is definitely my first passion. Always reading about new cars and lusting after some classics.

For me, besides my interest in building a Audio System in the past few years, I am also a Car Enthusiast and Amateur Photographer (actually I hate using that term, more like a photo enthusiast because I consider myself a novice).
All 3 Hobbies have taken much of my time, energy and money. Sometimes I look back and think, wow, what have I done?
Could have saved all that money and time.
So I guess I should list my gear if I am talking about other hobbies:

2016 Mustang GT 6 Speed (weekend car, a few modifications) and 2018 Subaru Forester XT (Daily Driver). Obviously both are performance oriented.

Camera Gear: Nikon D750 with Kit Lense, Nikon 50mm 1.8 Lense, Tamron 14-24MM 2.8G

Yeah I spend a lot of time playing and messing with musical instruments. Jammed it out last weekend with some other guys. I have way, way more music gear than hifi gear.
the road biking and surfboard themes resonate with me as well.  

I still have a few “holy grail” Italian frames hanging off the ceiling in tribute to my former king of the hill glory racing days.

 Also have at least 5 custom made performance longboards made by the top island shaping guru’s....Brewer...Lopez..Apia....etc....and a balsa gun for large Hanalei made by Gary Linden...all again from my former big wave glory days.
I work exactly half the year, I fill the half off with a few hobbies one of which is enjoying music, the gear is fun too. A large piece of rural Georgia property keeps me busy, very easy to stay isolated. My other interest include a few (fun) cars, a 1985 BMW 535 full of goodies, a 2015 MK7 Golf GTI that’s boosted up nicely. I like surprising performance cars with a silly blue Golf and some old dude driving. I have a larger turbo to install which should give me another 80hp and just 25lbs of torque at the wheels, right now I am putting down 320hp, 395tq, it’s my most recent toy.
I have always observed that appreciation for audio, watches, firearms, and vehicles seems to go together. I think it’s the appreciation of the engineering and quality of the build, could be wrong. I do travel a bit, usually somewhere off the beaten path and interesting. I spend a fair amount of time restoring audio gear, sometimes selling it, sometimes just for fun and giving it away.
My Porche 911 and my Porsche Cayman - I love to drive. They have the WORST stock audio system lol
