Due to the dearth of clear skies in the Chicago area for over a month now, I must assume that local astronomers have offended the great spirit in the sky. It has long been known that whenever a new telescope arrives, the sky will immediately cloud up. Obviously, then, many Chicago area residents received a new telescope for the holidays. Now if those clever folks at Meade, Celestron et al can come up with light pollution filters, then they should also be able to come up with a "cloud" filter. Since it is better marketing to put a positive spin on a product, they could use the inverse of that and call it the "clear sky" filter. For the techno nerds, it could even be relabeled as the "H2O vapor" filter.
In the meantime, a better solution (though about as likely to happen) is for all of us to form a caravan and head to Arizona. Who wants to drive?
