Clubs
Sarasota County Croquet Club -- The SCCC is located in Venice, Florida and the video above is a superb introduction to the club.
National Croquet Center -- The crown jewel of U.S. Croquet is located in West Palm Beach, Florida and features 12 full-size croquet lawns and a 19,000 square foot clubhouse.
Detroit Croquet Club -- This site has intrigued me for quite a while. Although some of the pages have never been filled with content and no updates appear, I feel the concept of what they are doing and the feel of the site is unique and possibly a promising way to organize a club. Would love to see this site be more active, but at the least, maybe by checking it out club managers can draw from the website design and format.
Associations
USCA Nine-Wicket Croquet Site -- I think this site is structured well and can be a key to developing the game across the United States. The site offers an RSS feed so you can stay up-to-date with the news section with your iGoogle or MyYahoo page or other feed reader.
Croquet New Zealand -- The association site for croquet in New Zealand which boasts nearly 4,000 members. A functional site that seems to be updated frequently. My favorite discovery here is the collection of PDF versions of their magazine -- Croquet New Zealand Update.
International
CroquetRecords.com -- This site updates the International, U.S. and North American rankings among other things. If you dig around, you'll find a good history on champions and tournament results as well.
Bowdon Croquet Club -- The club in England looks like a good model for running a large club. Of particular interest to me was the pricing scale.
Country Club Johannesburg -- I thought this South African site had a nice look to it and some interesting statistics on membership numbers for the commonwealth countries.
All links above will now appear in the Croquet Links section on the navigation bar at the top of the site. Any links back are greatly appreciated.
