How do you prevent ticks from sticking to your skin, getting inside of your tent, etc? Clothing, chemicals, tobacco smoke? Is there any special kind of clothing that makes it harder for the tick to latch on? Are there any chemicals that are natural and safe for you, but irritate ticks? Is there anything you can light and smoke out your campground or tent to repel ticks? What methods have you personally used that work, and what do you carry with you as a precaution for after you've been bit?
