Just don't put up posts prior to a race saying you're going to be there doing updates. That's what probably makes tracks more nervous than the actual updates you're doing and you do great updates. Just show up and do them. They'll be just as appreciated and you won't have drawn as much attention to yourself.

Myself, I use your updates as much, if not more, when I'm at that race than when I'm at home. It's like having a live, digital version of those programs they use to hand out.
