Yeah I dont know. I have had spider bites get infected and they looked similar. A particularly bad one had a large 7-8" ring with a center that looked similar.
Yeah we've talked about the Attlehole before. That area sucks unless you are targeted early like 1-4pm. Know it well; saw hundreds of storms 5-7pm crush ORH/even norfolk county and die as they enter the hostile sea-breezed, faded if existent sbcape.
