I've experienced this before, but haven't given it much thought before. My son and I hiked to a glassing nob to watch for bear. We were about 10 feet apart. The whole afternoon he had ticks crawling on him and his gear, 10+. I had 1. The next day we were 20 yards apart and the ticks were all over my gear, backpack and bino harness laying within reach, I had 5 on my bino harness and only 2 on me.
