I found this interesting article. Wellington, FL is considered to be one of the top names in the equestrian community. It's being reported that during peak season, as many as 9000 horses participate at the Equestrian Festival. That's fine. No second guessing on what comes out when we have so many of them in the town. Manure disposal is a problem that is plaguing the city. The article is a little old, but nevertheless, quite interesting.

So, Wellington, here we come!
