For a low annual fee you can protect yourself from the high cost of a tow. Not only are you covered for an unlimited number of tows per season, but your membership also gets you free towing on the Pennsylvania waters of Lake Erie. For an additional fee you can also purchase coverage for the U.S. waters of Lake Erie in Ohio and New York. If you break down outside of Pennsylvania waters just call the nearest Interlake Towing System affiliate, and your tow is still free!
