i'm working on a video from a vacation and several of the clips were in some windy conditions. any ideas on how to remove/reduce the wind in my video?

Difficult one, you could try using eq to drop out selected frequencies, maybe with keyframing you could try to get it to match the wind as it comes and goes.

Beyond that I'd have to defer to the experts. I've had the same problem myself and just decided to live it, the fly wire type grilles over the mics on cheaper cameras are carefully enigneered to make any wind sound like a gale I think.

If you do this a lot, you should get Sonic Foundry's Noise Reduction (I wonder of Sony bought that, too?). It will work with Vegas as a plug-in and does absolute magic on your background noises. I suppose, if you use your built-in mic regularly you have other problems too, like cassete noise, camera noise, your own breathing plus wind as well as household/environment noise. NR takes care of it. (Takes care of your LP collection, too, when you get round to burn it to CD.)
One trick is to not remove all the noise in one go, but run it though several times. You can have several instances of NR chained.

The best is to use an external mic and pad it for wind protection, but I guess you know that by now.

You can also just cut the windy audio and put in a voice-over talking about how windy it is or add some music, etc.

Sometimes it's easier to edit around wind noise than trying to fix it.

Removing wind noise after the fact is virtually impossible. It has a wide range of frequencies and it is constantly varying in level. EQ may help ever-so-slightly and an FFT-based noise reduction plugin, like the one SoFo offers, only works well on constant level noise like hiss or air conditioner rumble.

Oh yeah, by the way, just an old trick when you record and if you don't wanna spend a lot of money on some windjammer (or if you *forgot* your windjammer at home): just put a good old wool sock on your mic. Won't cut ALL the noise but hell of a good part of it ...
