i was wondering how safe it is to take the subway up to 116th and lexington then walk over to the costco by the river. should i take a cab from the metro station to the costco, or is walking fine? not really familiar with the area so i don't really know what to expect. i guess i could take a cab over to the one in long island, but if its not necessary, i would rather just go to the one in manhattan. thanks for the help
