Here's a link to how pollen counts are done. Interesting Stuff!
Pollens are monitored using a “Rotorod” pollen sampler or any other plastic rod or similar device that is covered with silicone grease.
I can barely see to do my bead work. The pollen count in Chattanooga, TN is classified as very high. Just how is pollen count calculated anyway? Is there a color chart you can match your vehicles to? My black van is now the color of Delica Bead number 160. Oh great, now it is sprinkling rain. Hoping variegated black and yellow paint jobs are in style.
