I've only been to the US twice so thought it was about time I put together a wish list of zoos to visit in America. I did this by compiling a top ten of US zoos using the book 'America's Best Zoos' by Nyhuis and Wassner. I first compile a top ten by using appendix one of the book. This appendix gives list of the best zoos in 20 categories (e.g. bird collection). First and second place are given but the remaining 8 places in each category are listed alphabetically. Each time a zoo appeared in a list I gave it one point plus two bonus points if it was in first place and one bonus point for second. Having come up with a top ten I turned to appendix two with gives two lists of the top 25 zoo exhibits in the US (one list for each author). I did a second top ten by giving a zoo one point for each top ten exhibit. The second top ten differed from the first so I did an average between the two lists to come up with a third and ultimate top ten American zoos. The top ten are as follows: 1) San Diego Zoo 2) joint second between The Bronx and ... Omaha's Henry Doorly Zoo 3) Denver 4) San Diego Safari Park 5) Brookfield 6) The National Zoo, Washington 7) Cincinnati 8) Memphis 9) St Louis That's 10 zoos in 9 positions due to joint second. Disney would have come next. Does it look a reasonable list?
