FREDERICKSBURG, VA.  Drove the short distance to the Fredericksburg KOA.  There is a Publix grocery store there, so we could not pass up the opportunity to do some shopping.  We also took Betty to the local NextCare urgent care outlet to have her right ear lobe examined.  A growing rash there was diagnosed to be a sort of shingles for which she was prescribed an antibiotic and another medication.  She seems to be doing better.
