I also like to take pictures (even though I'm mediocre at best) and go to the beach. I grew up on a beach, and 40 minute beach trips are the only downside of living in Riverside.
When I stay in, I spend a lot of time watching Netflix, or reading in my hammock. I occasionally work on software and hardware projects in my spare time, but doing that all day at work sorta burns me out on it as a hobby. I also secretly like boardgames a lot.
For vacations, I really like music festivals. I try to go to Bonnaroo every year and hit a few smaller ones nearby as well.
My favorite book is probably Dante's Inferno. I've read it 4 or 5 times. I also really liked The Picture of Dorian Gray and Starship Troopers (the book, not the movie).
I have lots of favorite movies. It'd be hard to pick a favorite of all time. Eternal Sunshine of the Spotless Mind, Pulp Fiction, Little Miss Sunshine, pretty much anything Wes Andersen made. As far as comedies, I really like Judd Apatow's stuff like Knocked Up. Forgetting Sarah Marshall was really good and I wish I could actually see the musical.
My taste in music is pretty eclectic. I can find something I like from pretty much every genre. In high school I went to a lot of punk shows like Strike Anywhere and Against Me. Of course, I also enjoy a lot of the 90s rock and grunge stuff, and classic rock too. Nirvana, The Doors, Led Zeppelin, etc. I also have some music which, while I don't think I'd be into it if it came out now, I was when I was younger so I still listen to it sometimes. Things like Blink 182 fall into that category I think. I also like rap. I like Wu Tang a lot, I was lucky enough to get to see them twice before they really stopped touring together.
As for TV shows, my taste tends to be a little geeky. I love the new Doctor Who, I loved Firefly. I like comedies, with The Office, Parks and Rec, and 30 Rock at the top of my list there. I also own the box set of Seinfeld DVDs.
