Welcome, Doug,
There's a bunch of us men on 3FC and more are always welcome.
We even have a
Men's Corner where we occasionally get fired up and grunt at one another. For the most part, we're spread around the different threads. It's not easy to tell gender by Avatar name and picture.
Here's the link to the
Weight Watcher's Forum - it's pretty active.
Good luck - having a clear goal like your trip is a great motivator.
