A goat post office sounds like a really bad idea. Wouldn't they eat all the letters? Is this zoo AZA accredited? It looks pretty nice.
The zoo has come a long way in the past few years, with a new Reptile House in 2009 and a new Education Building in 2013. AZA accreditation has been the long range dream and if I'm not mistaken the zoo is within a year or two of accomplishing that goal. I was pleasantly surprised.
