I have tried a few times and it is really just not attractive. In medicine, beards seem to be making a bit of a resurgence and I am seeing them somewhat more frequently over the past couple of years, even here in Florida. Distance runners as well, seem to go through phases of enjoying the growth of facial hair. Mario at Running.competitor.com noted recently that Ryan Hall has adopted the fashion, prompting Mario to review some of the great running beards of the past.
Additional note: The Art of Manliness just spent some time discussing beards and their impact on one's career/professionalism.
