Not to hijack things too far, but ever woke up with a 6 inch centipede in your SB or had a snake try to crawl into your SB, or to be covered with dozens of freakish wierd ant bites?
I have.
In this at times godless environment here in Australia, such creepy-crawlies are as common as mosquitos in Canada. Spiders the size of one's hand don't settle to good with me either, especially when they crawl into your boots. Then there is the mosquitos, and they come happy with Ross River fever, Denge Fever, and other unhappy diseases, then there is ticks which make you sick, causing lots of nureological problems, resulting in death if not looked after. Insanity!
So now, I do it the Aussie way (when the tactical situation dictates, which is most of the time). Although I pack a SB, and pad with my (yes a CF 82 ptrn) in my ruck for the just in case scenerios, in Corps other than Infantry, Swags are used.
Here is mine set up ealrier in May, up at Shoalwater Bay north of the tropic of Capricorn, in Queensland. May was a loooooooooooong month.
Everyone has them.
Cheers,
