Welcome aboard! What part of VA do you hail from? There's a ton of folks on the board from the great Commonwealth of VA. I'm in Hokie-land (Blacksburg). We'll be in Hampton for the shows.
As to the lefty-righty thing, I am a natural lefty but play right handed, as is gr8fulfred - there's a bunch of others some famous ones including one of my favorite guitarists, Steve Morse. I am an odd case as I went to catholic schools and had the "Sisters of No Mercy" beat left-handedness out of me so I do a lot of things right handed. I didn't know that there were such things as left handed or right handed guitars when I started playing and just picked up my brother's and went at it. Some folks make a conscious choice. Having your dominant hand on the fretboard has some advantages especially for a guitar player, for bass I would almost think that having your dominant hand playing the strings might be better as solid timing is most crucial for bass. I could be wrong, I'm a shitty bassist . . . I like to blame the nuns
Once you start down a path it's hard to switch up - I'm a total spaz when I try to play left handed. It is possible to go either way when you start, proof of this is the fact that they don't make left handed violins, violas, cellos, or upright basses (at least in the classical world) for the simple reason of orchestra symmetry - you can't have one lefty violin going the wrong way, it doesn't look right.
