I know how you feel...went through the same thing in July in Pennsylvania...we were only there one day of a week long stay when they ordered all parks shut down, we left, the next day they announced the budget was passed and the parks reopened the following day...but since the park we were vacationing at was a little over 3 hours away, we never went back.
It never fails to amaze me when state and federal budgets are at an inpasse or there needs to be cuts done, the shut downs and cuts always involve services that the citizens use...you never here the governor's mansion closing down or God Forbid you take any of the perks away from those in Congress.
