Attached are two elevation plots.

• 47th and Hawthorne
The high ground blockage for this path is only 1/2 mile away (in the 
area of 54th and Belmont).

• 45th and Main (the "best case" direction)
This looks marginal based on ground terrain, and trees may be a problem 
getting a straight shot.

BawFaw Peak, at 73 miles with a sector antenna pointing away from 
Portland isn't an option.
