This is as I thought... but I had been incorrectly told that LOS was
absolutely critical in establishing *any* link.  From what I can gather,
if the distance is relatively short, LOS becomes less and less important.

I'd like to set up my AP so I can get a signal in the park across the
street, but there are a few trees in the way.  The distance is fairly
short, though, so I imagine it is still achievable.
