But upon closer inspection, I find that each and every one of these flags has a business card taped to them, from Beth York Real Estate, out of Pembroke, MA but "serving Boston and the surrounding areas."
The card has the name of a local realtor, and her pic. She looks like a nice lady. But I'm going to email her to say that THIS particular method smacks of tacky opportunism. The 4th is NOT a vehicle for advertizing your business. Just mnsho. YMMV.
