We are also in a lockdown in the state of TN, except of course for "essential" things....the usual grocery store, Pharmacy, Dr. visits, fuel, going to work in an essentially mandated job. The way I see it, pretty much all of the above "essential" things put you at some degree of risk, depending of course on the amount of other human contact and the distance. Going for a motorcycle ride by yourself and not with others, to me, would be safer than any of the other things listed if you do not go somewhere that there are crowds and gatherings. I do think that we all need to use some common sense in this (which seems to also be in short supply like some of the medical items). Common sense tells me that a solo (or with the person you live with....husband, wife, etc) ride is not doing anything that would increase your risk to exposure, and in fact, would be less risk than grocery shopping. YMMV!
