AWP 2020, sparsely attended compared to the usually robust turnout in years’ past, was spread out on a soft teal green carpet that looked a little like grass. Rows of bright white tables, some empty, others covered in books and candy and tote bags, formed aisle after aisle. Planted in the middle of the broad avenues, where guests wandered, dazed or determined, were old-timey benches presumably for guests to sit and read under the fluorescent lights.
