Sightseeing on the mall.  2.5 miles from east to west, may not seem like a lot, but it is. You might want to work in some sort of transportation during your visit.

Bike Rental, Scooters, Crculator, Uber

Museums on the mall require timed entry

these visual mall map boards are around the mall. Very helpful

these images I uploaded mostly from my phone to dropox images monuments and memorials folder
