Generate a List of Free or Low-Cost Weekend Activities in Your Area

It's Friday, the weekend's open and the default is scrolling the sofa until Monday. This generates 15 free or low-cost things to do suited to where you live and what you actually enjoy, from coastal to city. You end up with a go-to list rather than another wasted Saturday.
