Hm, good points about 'eddy induced excavation'. That's a nice term.
I picked up the Spa-Flex today - $2.90/ft!!! Ouch. Hope I mentally measured correctly. (mistake#1) Unfortunately Canadapost's delivery dates were super-wrong, delivery is actually the 3rd now, so box building won't happen until Thurs/Fri.
This means, however, that I can go dig those Koralias out, see what's what. Maybe even go out and see some friends tonight. WEIRD.
