If you want to look at maps of how WNV is

It looks as though San Bernadino County is a little hot spot of WNV, not only in
horses, but humans & sentinal flocks as well. I don't know how quickly the
birds travel that are carrying it, but I'll be vaccinating my new horse for it
tomorrow. All the others already have had their 3rd shot (2 initially, and
booster this year) without any adverse reactions. I give the shots myself, in
the hindquarter.
