Well Menards had their grand opening today here in Springfield, and has the Polystyrene br-10 insulation closed cell foam boards I need for the floatation foam on sale for a bit over 22.00 a 2"x4'x8' sheet. That's around $11.00 cheaper a sheet than Lowe's. Even at the regular price it's still $9.00 cheaper...guess I'll be going this week end when momma gets home and getting me a couple sheets and getting that done...woo-hoo….
