The Sugar Land meetup is always on the second Wednesday of the month. The NW meetup was always on the last Wednesday of the month, before they kinda died in the middle of last year. Abel has resurrected the NW meetup, and I think he intends to keep scheduling them for the last Wednesday. That's what Sonny said in the last posting on the February meetup thread.
Now, I see that I was looking at the February calendar when I responded earlier.

The last Wednesday in March will be the 30th, not the 23rd, so if Abel is going to schedule the NW meetup for the 30th, then we could do the Katy meetup on the 23rd. Sorry for the confusion.
