Thanks for even more tools and tricks!

That app reveals what I was worried about, though - "ford" is barely used in the area.  And these concrete v-shaped waterways are basically like glorified gutters most of the time I've seen them - they're more or less a part of the street.  It's just in this particular weird case that the gutter leaves the street and goes through the median and then the park, which seems like it should be on the map...but calling driving over a small dip of a gutter a "ford" doesn't seem like a correct application of that tag, y'know?  For example, my street in NoHo is basically designed to become a waterway when it rains, and has these kind of gutters on either side. 
 Yes, you have to drive over them if you're crossing my street, but putting two fords at every intersection would be wild, no?
