Just giving this thread a bump...
Currently, those of us in the Omaha/Council Bluffs area are scheduling rides on a blog I threw together:
It's a little dead right now, having recently moved from the site mentioned above. I suspect it will pick up as the weather gets warmer.
I recently got a couple of throw-away computers from work, and I was wanting to host a website on one of them. So, eventually, we'll have a site of our own, and maybe a messageboard to schedule rides on.
Anyway, anyone in the area is welcome to join the blog, just send me a private message and I'll send you a blog invitation.
We try to get together to ride once a month. Our next ride is Saturday!
