Now that we have Approach Procedure chart images available on-line, does
anybody know of a URL where I can get WAC Chart images (or Sectional
Chart images) on line?

There should always be a fresh batch in "current".

I'd like to print a kind of strip chart for various trips that I take,
with just the route of flight and 30-40 miles to either side.

Plug in an address and an airport. Select a resulting "sectional route"
link.

(I'll make a better interface eventually but this works for the testing
I'm doing these days. Note that the red line is the Great Circle path.
I'm still deciding how to handle the difference between that and the
"straight sectional path".)
