Mountain and road riding, swimming, aikido, remotely controlled anything, and most of all, my family.
There are a number of people, but unfortunately mostly dead. John Lennon would have been very high on my list, and of course Da Vinci, but that's never going to happen. I would have really liked to have spent some time training with Morihei Ueshiba, or at least talking to him -- don't think I am fluid enough for that kind of training. I would love to spend some time shadowning Burt Rutan, just because he is so innovative... maybe one day, but he has graduated to such a different level, will probably not happen now. The list goes on, but mostly boring innovator types, so I am not going to list them.
Barenaked Ladies, De Lillos, Portishead, Mozart, David Byrn, Roxy Music, Morrissy, Me First and the Gimme Gimmes, Morten Abel, A Ha, Nina Simone, David Gilmore, Pink Floyd, David Bowie, Queen, Rachmaninoff, Allison Kruass, Nickle Creek, Grieg, Jack Johnson, Wagner, Jim and A.J. Croce, Coldplay, and much, much more.....
Grosse Point Blanke, Buckaroo Bonzai, Stripes, basically anything in that genre.
Don't have one.
