"Down time" has been quite a problem for me; less so as I get older. Assume you are referring to when in campgrounds. We try to get in 1 good walk of 40 min. or more each day. Read, watch too much TV if available, sit outside a lot, weather permitting. We check out the surrounding area and attractions with the car we tow. Always Walmart, eat out once or twice a week. Campgrounds are unpredictable when it comes to making friends. Sometimes make friends right away, sometimes never. Campgrounds with open spaces are best rather than ones where you are isolated from neighbors with vegetation. Winter's short days are tough because you camp to be outside.
