Enjoy your trip Sunilo! Airports are great for sketching.
It looks like Saturday will be a lovely day! Enter the park at the large wrought iron gate around 104th St and 5th Ave (EAST SIDE) If you bear left, we'll be meeting at the Burnett fountain at 11:30 am this Saturday. http://www.centralparknyc.org/maps/
We'll hang around the fountain area for about half an hour and move on after that. Perhaps to Harlem Meer or through the rambles on the west side.
Look for the sketchbooks!
See you then!
