Nice to know as I had never heard of them. Old guys like me just cannot keep up with the times. I'll take a look. If the fellows "make-the-cut" I'll add them to my favorites.

 

Mike Diamond is a driving force behind the site, although it's a collaboration. I'm on the place almost daily.

 

Mike gets my vote anytime.

Good golly that's about the most whupped die I've ever seen.
