In an effort to lure displaced Dan Ryan drivers, the CTA has again extended the period during which Chicago Cards are available at no cost. Considering how often they run this promotion, the CTA ought to do away with the fee altogether and just be happy they're making interest on all the balances they hold in escrow.

(In more sensible news, the agency's board approved a pilot program to offer passes to convention-goers, starting with the Gay Games in June.)
