I believe that only some brands of NOS have ingredients in it to keep it from being used as a recreational drug. I believe that NOS (Nitrous Oxide Systems in SoCal, PRK) were the 1st or 1 of the 1st to do that.
So it looks like NOS could be getting close to becoming illegal.
Notice that the only thing that the LEA system could get them for for the NOS was non-safe & / or improper storage.
Tis unfortunate though, as 1 of these shops, Midnight Auto, is not more than a few miles from my residence & I stopped in to see them along in that time frame and show them the turbo brick. They were old skool guys with a lot of '60's & up hot rod experience.
And yes, guard your guns.
The PRK would prefer non armed peasants compared to well armed citizens.
Natch that goes without saying.
They don't call it the PRK for nothing.
Could methanol shops be next?
