Been bouncing this around for a few weeks and decided to do it this weekend. Started a module for my upcoming layout. Went to Home depot and got 2 sheets of 3/4 (all they had) extruded pink foam and some spruce 1x4's. Built the frame and assembled with 3/8 plywood with 2 layers of 3/4 foam, cut my riverbed, put on my double track bridge and will be putting on more track tomorrow. Edited pics with paint to bring down the size for loading faster.
