Date men from United States / California / Foster City, 46 year old

Date single man from United States. I never know what to write in these things, but here we go!
I love to laugh. Since it's hard to quantify the type of humor I have, perhaps some examples will help: in the "musical" humor section, I love Victor Borge and PDQ Bach; in the TV section, I don't watch very much, but I find "The Big Bang Theory" quite funny; in the "Saturday Morning" TV section, I'm quite a fan of classic Warner Brothers (more Chuck Jones than Tex Avery); in the "watch with my son, but would watch anyway", there's "Spongebob Squarepants" and "Martha Speaks" (yes, really); Monty Python is always fun; and in the book section, Terry Pratchett (Discworld) and Douglas Adams (only the first three books) are nicely aligned with my sense of humor.
My favorite outdoor activity is running. I prefer long distances (8 miles or more) and I'm gearing up for even longer distances as I prepare to run another marathon in the fall (not to mention two half-marathons coming up before that). I love rock climbing, but I haven't been able to find the time to really get back into it (it's been many years since I've really climbed). I just signed up for some rock-climbing lessons to take with my 7-year old son, so that should be fun.
I've been going out more to hear live music in the smaller venues (The Independent, Slim's) lately, because there's something special about the connection with the band and the audience. It's also great to hear new bands that I never would have been exposed to otherwise (I was recently turned on to the Summer Twins, who opened up for Matthew Sweet).
I'm a voracious reader and I'm usually in the middle of reading a wide variety of books (and probably more than my fair share of blogs, essays, and tweets), with most of them on my iPad for easy access (and reference). I love words, playing with words (as in puns), and writing (I'm in the middle of writing two short books), which I struggle with because I take a lot of care (probably obsessively so) in finding just the right word to use. Alas, I can get easily lost in Roget's Thesaurus and forgetting about the great concept I was originally trying to express.
I play guitar and record my own songs on my digital studio (sounds impressive, but it's really just my computer and a lot of expensive software and gadgets), and even if nobody else likes it (let alone pays for it), I do it for myself as a creative outlet. There's really nothing like listening to one's own music and simply enjoying it.
So I realize I've written quite a lot about me, or at least the things I like doing and that make me laugh, but I haven't yet written what I'm looking for. Partially it's because if you found any connection to the above, then you might be that person. The other part is I after being married for 10 years and separated for almost 2, I don't yet have a clear enough vision of what I'm looking for to be able to put it into words. When I figure that out, I'll write more here.
