Darren,
Such good work! And yes, sometime I would really like to learn how to use the XRF gun, so I can just test the bridge paint for lead myself. Thanks so much. Nice photos, too.

Below are the test results for the bridges at and near West Thumb and Lava Creek. That worked out pretty well having me just test them since I was headed down to Lake yesterday anyway.
I'm forwarding you the video links for the XRF gun (they take maybe 20 minutes) and I will come by to train you on the XRF gun so that the next time you guys are planning projects and looking at work that needs to be completed on bridges and such, you'll be ablet to just check out the gun ahead of time, take it with you, and have the results right away (no more waiting on us - woo-hoo!). It really is pretty simple to use and would be a great tool for you to just take with you on your planning trips.
We'll go over how to check it out as well.
