Lucky you :)
Perhaps your right and I shouldn't lump them all into the same category. However,
people I have worked with and myself have not had a pleasant experience with advertised positions. One job I was flat out lied to about the situation. The horse world is fairly small, later I ran into a gal I went to school with at a show, who went through the same thing with the same trainer. Not the only instance...
The best jobs I have had were the ones not advertised but rather through a friend of a friend type of situation. And yes, no matter what, whether it be the internet or word of mouth, do your research.
I DON'T LEAD 'EM AND FEED 'EM, I RIDE 'EM AND SLIDE 'EM.
