Since an off-field landing in an EZ could be the death of me,
I've been doing this lately:
R = (cruise altitude - field elevation) * glide ratio / 6076
R = glide distance in nautical miles.
cruise altitude and field elevation in feet.
I calculate the glide distance for every airport on my route,
and draw circles on the map. The more these circles overlap,
the better.
I recently found I can cross the Rockies up near the Canadian
border, no airports over 3000 ft. elevation and the distance
to cross is minimal. And there are more airports up there
in northern Idaho/Montana than there are in Wyoming, where the
field elevation is typically 7000 ft, severly restricting glide
distance.
Since I'm already so far north (near Portland Oregon) it's not
that far out of the way.

Be great to have you at OSH this year Perry. Would be wonderful
publicity in the aviation press. Here is a picture of Perry's
13B powered airplane for the new guys.
