Cloud Covered Milky Way

The new moon is upon us, which means prime astro-photography opportunities.  I checked the weather as the sun faded under the horizon and decided to take a drive to Itasca State Park, as it is the darkest sky near me , to see if I could photograph the Milky Way.  The best time to see it was just after Midnight for roughly 2 hours before the center also fell to the horizon.  I arrived around 11:40 in order to have time to setup my gear and begin shooting.  Things were looking great until about 12:30am, when wispy clouds started showing in my 2 minute exposures. By 12:45 a cloud bank had blocked the entire Milky Way.
