A two-hour walk from Sukhumvit Soi 2 to Soi 23 – which includes both the Nana Plaza and Soi Cowboy red light districts – found Bangkok nearly deserted. Bars were dark, of course. but the extent of just how deserted the streets were, how empty the BTS was and how desolate the MRT stations were between 6 and 8 p.m. still proved hard to comprehend.
