Glad to see somebody took the initiative here

Several electronic road construction signs around Anchorage were hacked late Wednesday night or early Thursday morning, according to the state Department of Transportation.

Signs that normally display closure and detour information, like the one on Minnesota Drive near 100th Avenue, were changed to read “Impeach Obama.” That particular sign wasn’t fixed until sometime between 6 a.m. and 8 a.m. Thursday.
It happened because DOT says it doesn’t lock the boxes on the signs that hold the message control pad.
The Alaska DOT was not happy:

“I’m sure somebody thought it was a pretty funny joke but we try to convey a lot of important information with these signs,” said Tim Croghan, a regional construction engineer for DOT.

What could be more “important information”?
