Right! The only tricky part will be to keep the rollers from dropping down
between the plywood sheets. Having the sheets run at an angle to the
direction
of motion would be a big help. If the ground is really soft, you could
stitch
a 2x4 under each junction, and it would just push into the earth and
allow the
sheets to stay together.
