Hi Derith and Mombo:The sit by Elinor DeWire was real good it explained day marks in good detail.Thank you mombo for posting it.Now while on the day mark subject here is a story told me by an old friend from St.Augustine who taught school for many years.This tale purports to tell how St.Augustine light got its distinctive swirl design.It tells that at one time the light had vertical stripes and they were in need of repainting.Wellthe keeper got all his paint and gear out and got to repainting the stripes When he was almost finished a warning of a gale wind came through and he hurried to finish and put his gear away and sure enough a very strong gale swept thru and the paint had not yet had a chance to dry and when the gale had passed the wind had twisted the vertical stripes around the tower to the twisted pattern you see today.Hope you liked the story.Bill O'Brien
