What would you consider a Templestonian?

As a longtime "Templestonian" I would have to say someone that likes wide open spaces, rather than claustrophobic blocks of land, is more likely to have a family with kids (rather than a single young professional) and someone that likes a multi-cultural environment.

I am, 15 years living here

I think anyone who has lived in Templestowe for more than a few years. So many great memories riding my bike around as kids exploring.
