Charleston at sunrise during the summer isn't any better with regards to no-see-ums. While driving out to setup a Hobie 18 one morning (trying to beat the people that park and block one of the few beach accesses on Folly) he told me that we could probably only withstand about 20 minutes at a time before we go "full monkey". It took about 10 minutes before we both were running away while jumping up and down waving our arms over our head as those f'ers devoured us.
