When you say "pruning" what exactly do you mean?
Pretty much just deadwooding, Mick. Our corporate term is "crown-clean," which is supposed to entail removal of deadwood, and all crossing branches. I started out down the crossing-branch road, and the neighbor threatened to call the cops if I cut out "one, single, more, green, little piece." That made me cease and desist. The guy was darn near as old as the stinkin tree so I figured I'd just do what he said. Kinda dumb to cut much out of those oldies anyway.

Joe also got me trying to get a dbh via the Van Pelt method...
Photographic evidence that it's a pig...
I took four different measurements to try to get what Van Pelt would consider "breast height," and came up with 21' 2" circumfrence twice, and bang-on 21' twice. We'll go with 21' circ. The higher math pi division puts ya right at 6'6 and 3/4" diameter. My estimate was off by 3/4" dangit. Pig anyway. Here's the after pic off my crappy phone...
