Ehrlich gives green light to Santa
By Gary Emerling
Yesterday, Gov. Robert L. Ehrlich Jr. issued a proclamation declaring Santa and his team welcome in Maryland on Dec. 24.
"All flying reindeer, including one with a red nose that glows, are permitted to enter the state of Maryland's airspace during the very late hours of Dec. 24," Mr. Ehrlich said.
The proclamation pre-empts a law that state wildlife officials said is necessary to protect the deer population in Maryland from chronic wasting disease, similar to mad cow disease.
The prohibition against bringing live, hooved mammals into or out of the state was passed in 2003 and is punishable by a $125 fine -- meaning Santa would have had to cough up some cash if the authorities caught him crossing state lines with Dasher, Prancer, Blitzen and their buddies.
