There's this French-Canadian guy named Ben who's always up for a good project...

Seriously, though, never underestimate the amount of weight, mostly from
water, in a tree trunk or limb. They fall in the middle of summer, too,
when it suddenly gets hot; the tree tries to suck up more water to protect
itself against the heat, increasing the weight.  There's absolutely no
warning, either. Ask how I know.

Sorry about your Westy. It looks like a nice one.
