Thin sheets for fence and bridge

I can imagine the thin sheets on the fence and bridge will get pretty beat up during practice. It would be nice if they were available for individual purchase, I use our field to run tournaments and It would be nice to have a fresh set for each one. I might use card stock for practice matches and just put on the plastic for tournaments.

Also, it would be nice if the goal markers were available too for anyone that wants to put them on both sides of the field.
