For a change of pace let’s test out the Mall proper again. There is a chance the park rangers are still patrolling. If so, it means turf shoes, or you’ll have to go barefoot. But the flat, soft ground, with full grass cover is a nice change from the hard uneven ground by 17th. The field closest to the metro stop should be open. If not, check fields successively closer to the capital building.
It’s going to be hot and moderately humid this afternoon so bring plenty of water. Conditions are right for an afternoon thunderstorm, although less than 50% chance of rain predicted. An umbrella is still advisable
