I know right?

The years is probably higher than the parking lot but you can't see it from the angle the picture is taken from.

The wood swells with water, effectively sealing holes and reinforcing the fence.

What guest was trying to say is that this person's yard and fence is above the water line but because of the angle of the picture it looks like the fence is keeping the water out when in fact it's not even touching

Ok that makes sense, because that's a shit-ton of water pressure going on if it was underwater
