If the visit is only aimed at having a short look at inside the barn, check the farms records / water tank / lighting, (1) they may even not have to enter the barn, and a window on the door could do the trick (2) or “easy to put” (not requiring the use of hands) gardening clogs could reduce the time dedicated to changing boots. Just like when you like to reduce the time needed to put your slippers on!
