DTR all the way (Dry Tree Research) :)
Sounds like you have something in the way of a DTR3 out your back yard! Good man :) There is heaps of potential development in this feild. I was thinking of writing a DTR guide to the best problems in Wellington, but then I moved.
One important rule in DTR is that it must be done in the dark. Best conditions seem to appear at around 1 am when a party gets a bit boring.
