We havn't been around that long in our current form really, so I guess that plays a part. People also tend to just stick to whatever forum they are already on too, and while there are loads of older enthusiasts, it's more the 'kids' that are into parks really.Also, TPM does tend to attract people when they are kicked off other forums, and those people tend to be young.Combo of things I guess, would type more, but my hands ache!
