Soggy cabbage...you're incorrect.
People do stop on along the shoulder to watch aircraft come in. The approach is an everyday occurence, althought this guy was lower than most. Several roads from various sides of the island converge at the top of this small mountain, which just happens to be the point of approaching a/c before they have to do a quick descent onto the airstrip at the bottom. I've never seen an approach on the opposite end, so my guess is there's one way in and one way out.
