Nice thread! Some members spend time in really interesting ways.
What I consider from always my main hobby is reading. Sometimes I also read publicly and organize public events related to poetry/literature.
From the sports point of view, since some year I do running, also competitive. I run up to the half marathon, although this year I also tried mountain running (skyrace).
(funny: in one URL I wanted to link, one piece is being censored automatically... random generated URL by Picasa is perhaps oscene)
The arrival of a relatively short skyrace (12km, about 1000 meters of rise). I had my cell phone in my bag taken there by organizers, so I took a picture.
I also play bass guitar, and once a week I play with friends (rock/pop, the last one we started to prepare is Karma Police, Radiohead). Never publicly, since our quality is not adequate, however it is an extremely relaxing evening I would never renounce to.
This is not me but the bass is mine (I was taking pictures).
And recently I re-discovered two old time passions.
The first one was r/c airplanes, 4-5 years ago. It is someting I just tried as a kid, but I didn't have money for it (shifted to cheaper to static modeling for some time, but less motivated). Now I have money but not time...

Actually, I like building (balsa, but not only) much more than flying, so my best constructions are then maidened by an expert flyer.
I liked photography at the university times, and then started again a couple of years ago. Last summer, a decrease of free time (plus 3 crashed planes in my garage

) stopped me from building in favour of photography... I hope only temporarily, because building airplanes is very relaxing.
I have some preference for old airplanes.
Reggiane RE2005 "Sagittario" before covering.
Fournier RF-4. Actually, this one has been published on a UK review, because it was the beta build of a project from a known british modeler. Ironically, I crashed it before the review was out. I did it from scratch, but after that an US manufacturer prepared also the kit, if you like one

.
I also build in depron (extruded polystirene), for easier models.
This one is a Demoiselle by Santos Dumont, 1908. With this one I won a competition started from a modelling forum. It is my last building, more than one year ago.
I hope that winter will give me some more time for these things - better than playing Sudoku.
