Thank you for these excellent suggestions. I agree we should donate some dollars, easy to send to the Friends of the C&TS. They are planning to organize crowds in Antonito.
And cheers for a brilliant suggestion to keep cars tucked away from sight! I am counting on the brotherhood of foamers to take pictures from all angles. I also add drones to the list. BTW it is against FAA regulations to fly drones over people unless they are part of the designated flight crew, or to fly over moving vehicles (presumably a moving train is a type of moving vehicle).
