Good article and advice to post on this forum, Glenn, as many smiths are using these tanks for their gassers.

The anhydrous ammonia is used in one of the processes used to illegally make methamphetamines, actually the process is the most dangerous of these processes. The use of the tanks are very prevalent in the midwest where there are large bulk tanks from which the "cookers" steal it from farmers. What's more, they usually transport it in the trunks of cars, or bed of a truck, unsecured. They use the tanks as a means to avoid detection by the authorities. Disaster waiting to happen. Use in this way is a matter of WHEN will the valve fail, Not IF.

At least this is what I have heard at a few seminars I've attended.
