Removing wind noise in post

I recently shot some footage in a woodland area using a lapel mic with sponge wind protector and a second shot at the same scene using a hand held Sennheiser ME44 with deadcat. the end result is still a lot of wind noise - about equal in either shoot mode - actually, it is perhaps more accurately the rustling of leaves in the trees as well.
as wind

Whilst I don't mind some noise, afterall it is woodland, there are times when the narration is slightly overpowered by the noise, is there anything I can do in post production to reduce this background noise.

My NLE is Sony Vegas Pro 9.

I'll assume you don't have any kind of NR program, so, you need to find the freq that the noise is. I would find some of the wind without any other sound behind it, split that part of the track, you can recombine later, then goto Non-Real Time FX and try the Track EQ on that clip. I would goto the #2 tab which makes the blue dot red and pull it down to about 150 with the gain set to about -12 and the bandwidth to about 1. That's a starting point, play with it from there, and see what happens. You might want to try some combinations of #1 and #2 but I think #2 might be the one. Oh yeah, once you have what you want, save it as a preset, makes it a lot easier later.

Roll off the bass end at around 150hz, boosting the mid and highs a little will help pull out the voices.
Have a listen to the High Force item on here:iNorthEast.tv

It is two G2 radio mics in a strong wind and I used the above filtereing to remove the wind noise.
