Richie C - That could work. I would need to buy three sections.
Alan - Let me see if one of these other ideas work. If not, I may take you up on your offer.
Pete - I have played around with carving foam. Since this hill is made of 2" foam board I could carve the stone right into it. That's an option.
AlanRail - Where did you find that stone tile? I looked in Lowes and Home Depot and could not find it.
Thanks for the help guys.
