We know it's a bit personal to go around guessing someone's weight, but this is a bit of fun and all for a good cause... so tell us how much you think Moses weighs! Just £2 a go - email your guess to email@example.com. If multiple people guess the right weight, all the correct answers will be put into a hat (or possibly a bucket!) and the winner chosen at random. The prize will be an afternoon tea once our Visitor Centre is able to open to the public again.
