When I was inviting friends to be a part of this, there was a big divide... half of them LOVED the idea and felt like an island was something special (as I do), and others just saw it as some difficult-to-access land. I've had a tough time articulating exactly why an island seems special to me.
Also most human cultures either grew from river or coastland - the availability of fish and other resources that a large body of water provides is very comforting to us descendants of those peoples at a very basic level, I imagine.
Is this the beginning of a horror movie or a comedy?
Seriously though, owning an island is awesome. Have fun and be safe. :)
Proof: Would you get excited about a story of someone buying a five acre plot of land with a fence around it? Or a moat-like trench?
Yup, that's a +1 there.
