Hi Yellow! I talked to a couple of people without contacts that said they had the halo thing last year on Lotoja but they thought it was because of the snow. I asked one of my doctors here. He said "you rode your bike 206 miles and you want to know what is wrong with you?" Ha ha. One real theory is that dehydration can cause swelling and if they eye swells enough it can cause weird vision things.

BTW I'm glad you are okay from your mountain bike fall. I spent a lot of the summer avoiding the mountain bike just for that reason. Now I miss it!
