Sudbury police used a man’s cellphone to help him find his way out of the woods. The man was cycling on a series of trails in a wooded area north of the city on Monday when he got lost. The man tried for several hours to find his original trail but got tired and called 911. A search and rescue team found the 48-year-old after police triangulated his position using his cell phone. The area where the cyclist was lost is swampy and shrub-covered.
