Protection from bug bites. You may not think you need it, but when you do you'll be glad you brought it.

For bug repellant, the tried and true advice is the more DEET the better. For the most part I've found this to be true, however you don't need the super strong stuff to be properly protected. I used to use Sawyer's Jungle Juice 98 percent DEET repellent, but after some excess juice on the bottle burned a hole in the plastic bag I decided to do a little research and found this is a much better alternative. If you want stuff that really works, and don't want to worry about reapplying every few hours, this is a good choice. Plus, a low percentage of DEET makes it safe enough for the entire family to use.
