MARBLE SITES TO VISIT
Listed below are some marble sites that I like. The list is by no means exhaustive. As the Dos Equis guy would say "I don't surf often. But when I do surf, I surf these sites. Stay Mibby my friend."
All About Marbles is probably the biggest and most active marble forum or bulletin board. The moderators keep a pretty tight handle on things, so if you're looking for flamewars go someplace else. Check it out, it's worth a trip.
Mikes Marbles has been around for a long time, since 1998. His home page refers to it as the "8th Wonder of the World"! Mikes a teacher and you've gotta love someone who takes on the task of teaching our future. Check out his site, he has some really interesting articles and pictures on it. You won't be disappointed.
Here's an interesting concept. mibcollectors is a website where you can post images of marbles in your collection for everyone else to see. Each page on the site is a different collection. Truly unique.
