I'm with Suga, we have so much pollen, we literally can sweep it up. I pulled up beside a pine tree one windy day, and there was a heavy cloud, so thick I could barely see. It was unbelievable. I don't recall Spring allergy season being this bad. The pollen index charts are off the chart already, and spring has barely begun. Add to the pollen problem, windy March. It spreads it everywhere. Unless your car is in the garage with the door down all the time, or you wash it everyday/several times a day, it's going to be greenish for quite a while. It's a good thing that my little town has it's own wastewater treatment facility, otherwise, our water bills would be astronomically high, as my DH is one of those fastidious ones.
Here's to rushing spring along.
