i like your entire analysis
& would only diddle tho not quarrel over this last point
since clearly you are right in meaning that the darien gap as a whole has
not been bridged by a road yet
but i have been monitoring this hole closely over several decades now for
any sign of closure
since it would be so much fun to just jump in the car & drive down to rio
for the winter
or rather for the summer
& tho that will never happen now until coke is legalized
the gap has been whittled down to about 10 miles i think
which is a huge difference from when i visited there in 1967
albeit with no apparent change since message 596
but the point is
the missing part is now entirely & deeply within panama
the colombia panama boundary itself is crossed by a thru road at least once
as you can see on multimap
& likely by local roads in the several border towns also shown there

how could we forget now
but tell us
what was it again
