I was idly browsing on ebay one day and my wife looked over my shoulder-
Why are you looking at tanks?
I thought i might buy one
Where are you going to park it?
In the front garden.
What will the neighbours say?
If I've got a tank, they probably won't dare say anything
But 'seriously', if money were no problem, I think I'd be like a few on here and start with a very large building to keep a collection in.
