One goal I have is by the end of this year is to be able to do a bike tour to a nearby camping ground. Of course, I will be carrying my usual behemoth U-lock to ensure that my bike remains put. However, for the backpack and tent, should I see about either using a PacSafe based backpack that has a woven steel mesh inside and can sort of  securely be anchored around some object, or the normal backpack/panniers and a PacSafe bag protector (which is steel mesh where you stick your existing stuff inside, cinch it shut, then lock it around some sturdy object.) Am I assuming the worst, or is having stuff locked down a need at parks or campgrounds, in peoples' experience?
Firsthand, I've not had anything disappear, but I've not camped out in a long time. However, a family member had a tent (and everything inside) stolen when he went out on a hike before. Thankfully, he kept his car locked and his keys with him, so the car and the contents inside were still there, but all his camping gear was ripped off.
: Well, securely as in someone will be hard pressed to obtain the contents without resorting to tools.
