If Del. Maggie MacIntosh wants to make sure the legislature "does it right" in determining if gas drilling by the hydraulic fracturing method is allowed in Maryland, she should heed the warnings given her committee by John Quigley in his testimony describing the wave of problems it is creating across Pennsylvania ("Md. lawmakers warned of natural gas drilling woes in Pa.," Feb. 10). We know. We have a home there.

Note, too, that Mr. Quigley describes chemically-laden gas that erupted in the Susquehanna River. Remember: that river flows into the Chesapeake.

Montgomery County legislators have the right bill: bar drilling until more is known about the entire process. Pennsylvania didn't do that and is suffering the consequences. We could too.
