I'm behind you 100% on this, Juice. I have used this stuff for years, and it works very very well. Here in NH, we enjoy the distinction of being the #1 state for Lyme disease, and we got EEE and West Nile Virus as well. It pays to keep yourself protected.
I wash my pants in Sawyers, and wear Bug Off shirts and hats. When I am hunting the woods, I wear 16" tall Muck boots when its wet, and Cabela's snake boots all the other times. The best part about wearing the tall boots is that all you have to do is tuck in your pant legs and spray the boots with some deet. You can actually use the Sawyers heavy-duty permethrin spray on your boots. This will take care of 90% of the ticks you encounter, but there are also some ways to prevent coming in contact with them that many people dont think about.
When walking through the woods, try to avoid brushing up against bushes and branches. The modus operandi of ticks is to position themselves on leaves and branches and drop onto animals that brush up against them, thereby finding a host. Also, if you kneel or drop to a knee to dig, then you'll be coming into contact with crawling ticks. This is why its so important to spray your pants and wear long sleeve bugoff shirts.
