I was wondering where I could find this competition as I might be able to help or could you send a couple of the questions that are causing you problems. I might be able to answer them for you as I used to be in the travel business.
Think I have 23, but can't get obvious bell clue or monkey thing on the mountain. Also not sure about Bison, but it's definitely a Bison not a Buffalo! They're in North America, but that's a bit vague..
