I doubt that very much - although we can't stray that far, my other half, Brambles Dad is a 34 year old male (short haired blonde hamster enthusiast-not up to show standard unfortunately lol) and the shows we have gone too seem to have a mixture of age and sex from probably about 10 to 50 (and maybe a little older - but wouldnt want to be rude)
As you'll see from the posts above - I'm sure you'll have a great time, and certainly will see some gorgeous hamsters....
......talking of which - I got a similar pm to you earlier about a certain website.....
I hear you are thinking of taking one? I think that's a really good choice! You will have to let me know what 'flavour' you are going for. I would find it very difficult to choose just one
