NO cross-country skiing on BART

Unofficial BART rule

Last week I got on BART, turned around, and noticed an unfamiliar new rule: “NO cross-country skiing” according to a sticker on the door.

Now at first glance this seems pretty reasonable, but of course it’s one of those rules that should go without saying. For example nobody needs to be told that on BART they shouldn’t practice golfing, perform dentistry, or experiment with nuclear power. Common sense, right?

So then I turned around and noticed the same sticker with its original caption:

Official BART rule

Oh. Well that makes a little more sense.
