We were also there on the 26th. I heard that some people were having issues and were being sprayed with vinegar at the first aid station, but nothing major with us - maybe a few "mosquito bite" type sensations while in the water? Two days later, DD16 said she was itchy and had a few insect bite type bumps on her arms and legs, but nothing that an alcohol wipe didn't solve. Not really sure if it was a Sea Lice affect or not.
