So I have been wondering: 0B5 has sayweather, and advisory weather system that broadcasts over the UNICOM when requested by pilots. However I am unable to find this actually listed anywhere, for example the AFD, remarks area of foreflight, I don't know where else to look. There's a few other airports in my area that have systems like this, and you're just kinda expected to know that they have them even though it's not (as far as I can find) publicized anywhere. Where should I look?
