We know at least one BARFer that had a 'close encounter' w/ flushable wipes 

Officials with the District of Columbia Water and Sewer Authority say that more than 500 man-hours have been devoted over the past 12 months to removing stuck wipes and repairing broken equipment. Anne Arundel County, Md. officials blame wipes on a 35 percent jump in broken pumps and clogged sewer lines over the past several years.
The wipes also contribute to blockages that cause sewage to overflow into streams and back up into basements.
