Unfortunately for me, the masks drive me crazy. They itch, get wet, get hot and what not and make it hard for me to breath and fog up my glasses. I cannot imagine wearing one for 3-4 hours for a train meet even if I would love the meet. I do it for groceries because I have not figure out how to get along without eating, but so far I have found it palatable to do just for the fun of it.
Besides, there would probably be very little 2 rail there anyway.
