Nice work, @clairem38. Visual impact from ten feet, my foot.

Absolutely! I had the same panic in London at first. Two days later I was hopping lines like a local and felt so proud of myself.

How deep do they usually dig to get those soil samples? I always thought pollen was just a sneeze thing, but it's wild they can tell apart wind-pollinated crops from insect-pollinated plants in old dirt. Basically changed my whole view from "ugh, pollen" to seeing it as tiny time capsules.
