Cash Station machines are posted near the entrance. That should give you enough for train or cab fare. The pier's parking garage takes credit cards, but all others take cash only. However, if you want to stay for fireworks, remember that the trolleys stop running at 9 p.m. Sunday through Thursday, until midnight Friday and 11 p.m. Saturday. Come prepared for sudden cool lake shore breezes or showers.
Weather can change in an instant.
