Podcast Idea: aminopyralid persistence?

Heya Paul, love the new stuff you're putting out!  Here's a freebie show/cast idea that might concern a lot of people: aminopyralid contamination.

If you do container gardening, and if you gardened last year AND had trouble like I did, then your containers are contaminated....so:

1) Can they be cleaned

2) What trace levels would remain? (which leads to the general question...)

3) Absorbability in plastic?

Thanks and keep up the good work!
