Black light prospecting

[oldprospector]

Approximately one week from today (May 5, 07) I'm head south and east from the Mcminnville area to do a little black light prospecting.
Any suggestions?
Thanks

The Clackamas river, just south and east of Estacada, has petrified wood, bloodstone, jasper, agate, and common opal in it. Not sure if any of these would show up under a blacklight.... maybe some opal would.
