For news and info with great editorials too go to
www.equidaily.com
Seth does a great job of compiling racing news from all over the world into one site. IMO, it's the best all 'round racing site.
The major racing news sites are
www.bloodhorse.com and
www.thoroughbredtimes.com as well as
www.drf.com for news and great handicapping info.
If you can get either TVG or HRTV or a local OTB TV channel (in NYC and Albany NY, for example) start watching races. Sites like this one are a great place to ask questions about things you see.
Welcome to the game!
