Pugwash,
I survived the 1980s just fine, thank you, although the "me too" movement and lame music scene almost drove me to jump off a bridge. Actually, I survived the 60s and 70s, as well. I'm told that I had lots of fun.
  Yes, there are 28g/oz, except in metals. In that case the conversion is 31g/oz. As you may recall, the price of metals peaked in the 1980s. I was living in the Sierra at the time, mining gold. Troy ounces are a little bigger than an ounce avoirdupois.
  A loonie is 7g? Do tell. A US nickle is 5g, which gives you five grams for five cents. That makes it easy to check the accuracy of a scale.
  You may
not carry a bottle of 151, or any other high proof liquor in the cabin of a US aircraft. See 49 CFR 175.10(a). It's against FAA regulations, and has been for years. Naturally, the TSA (Thousands Standing Around), is ignorant of FAA regulations. They only half understand Homeland Insecurity regulations, and they're not going to worry about the FAA rules. Liquids over 3oz are not allowed. Exceptions are liquids purchased after the security checkpoint and medical liquids like Harriett's.
    Dan
28 gramms to an ounce!
didn't anyone else survive the 80's?
I can't figure why you can carry a bottle of 151 (basically Fire Accelerant) but not Habanera Jelly?
