Yes, The sticker shock is bad at the pond places. I talked to a nursery in
Seattle today and was quoted $10.99/lf for 13' wide material & $14.99/lf for
19' wide material. This is around 80 cents/ sq. ft. I then talked to a place
called the Bambo Place north of Seattle. The lady there very cheerfully
offered to sell me a 5'x5' size peiece for $35. A $1.40/sq. ft.
Been trying to get with a local roofer. Said he would sell me a reminet of
65mil for 50 cents/sq. ft.
It may have stuff on it but the roofing grade is the ticket for me. Shoot i
don't have fish or plants (anymore), the pond is just there to entertain the
Coons & Herons
Hey John where are you getting your material?
