The presence of so many mosquitoes at dusk makes it a good idea to carry an empty 32oz Gatorade bottle. If you need to pee, instead of unzipping the tent to face hordes of mosquitoes (and
inevitably letting a few inside), just pee in the bottle. Use the bottle if it's cold or raining outside too. Gatorade bottles have wide mouths that make it easy and 32oz is a good size in case
you need to go again later. Women can even do this if they use the pStyle.
