This includes architects and builders, artists, awards and trophies, employment, gifts and jewelry, insurance, pest control, photography, real estate and the ever-vague other services. If you design web sites, create software or CD-ROMs, or do any of that geeky kind of stuff, your web site belongs here. The HayNet, put it in this category. Or if it's so broad in scope and general in nature, it's gotta go here. If you use it to make your horse more beautiful or make his feet stronger, if it comes in a bottle or a jar, or if it's perishable or you use it up, it goes in this category.
Any site devoted to harness racing, either commercial or informational, goes in here.
Here you'll find links to general racing resources and news sites, as well as links to specific races and tracks. There's also a large and steadily growing section on commercial sites devoted specifically to racing. These sites are organized by breed, discipline and region. Sim games and many fantasy games go in this section as well. Most mailing lists have web pages these days.
