Is the gnat bite on?

We're watching Day 1 leader Ott DeFoe fish this morning. He's had one fish come off. Otherwise, no bites for Ott so far. On the other hand we are getting eaten up by gnats. Here's a photo of a bunch of gnats on Crispin Powley's hoodie. On our boat we're pulling up our buffs to cover up from the gnats.
