as i was unloading a bike from the truck in a downpour...i nearly slipped and busted my ass on the wood ramps. Luckily i was home and could grab my trusty dewalt drill and a handful of screws. I spent about 15 minutes driving approx 50 screws into the ramp i needed to walk down. I put them in as rows of 6 accross the board and spaced the rows 6 inches apart all the way down the board. I noticed that i had to back out a few screws since the driver tended to countersink the head. When they were all in and above the surface of the board, it turned a wet slippery board into a nice easy to walk on surface.
