IADMIRE PennDOT's efforts to make sure that only those with valid Social Security numbers can hold a driver's license.

Have we forgotten Sept. 11? I haven't.

I got my valid driver's license in the very same building that seven of the 9/11 bombers fraudulently got theirs. Pennsylvanians - and all Americans - want only those validly here to have licenses.
