I was thinking about this issue this past weekend at an outdoor show. I had to deal with rain and wind. I always leave my CA windscreens on but I still got a bit of rumble in my recording, but it's not terribly noticeable. There was some intermittent rain, but I had a plastic bag handy to cover them up. Probably would have ruined the recording, but I since the stage wasn't covered, I figured the bands would leave the stage if it got too bad. I had my gear bag in a plastic bag with my camera so everything stayed dry. It never rained hard, luckily. Does anyone make very tiny dead rats? rWc3523
