[Just_Build_It]

Hurricane Hermine really messed up the ground and caused minor erosion to the unfinished tunnel and really partied hard tossing sticks and branches everywhere and now I have to remove a fallen oak tree from my backyard.
I'm still tossing idea around for a highway . I can't really decide on what to use, other than a more permanent cement highway.
1: cement- great long lasting flat surface but permanent
2: foam gym mats- long lasting, interchangeable not as flat on dirt and costly.
3: laminate tiles- another long lasting, interchangeable, not as smooth on dirt, not interlocking.
4: tar paper: not great on dirt and not very durable in the Florida weather, cost effective, nice scale appearance when affixed to sub floor, easily changeable layout

Any new ideas or input will be greatly appreciated.
