Save your data plan or the cost of a cup of coffee at a wi-fi hotspot. Visit the bookmobile instead. The Jefferson County Public Library has added FREE wi-fi to its Bookmobile for patrons to download free books, magazines or stream music and movies while they visit. Download and print the Bookmobile schedule here (it visits dozens of sites every week) or park near the vehicle every Saturday at the Safeway on 12442 W. Ken Caryl Ave. (at Shaffer St.) from noon to 4 p.m.
