Will they need to call for help because they are under equipped? Will someone need to loan them gear?
I am not a risk taker so to avoid the risks inherent in walking say the Western Arthurs, Federation Peak, and the Gammons (northern SA) I spend a lot of time planning. In fact, I enjoy the planning almost much as the walk! I look at the weather statistics, read reports on blogs and forums, talk to people in the gear shops and in the two bushwalking clubs to which I belong. I use Google Earth to view the route, study maps, check Flickr and other photo galleries for photos.
Then I pack accordingly based on the expected weather, terrain, isolation, potential for accidents, food requirements.
Many times, my pack is heavier than some others in my group but I know that
- * my tent won't blow down or collapse in a snow storm
* my gear will stand up to pushing through thick scrub
* my boots can withstand the rocky outcrops
* if my waist belt breaks I have a spare buckle
* I have sufficient food for at least an extra day, if creeks are swollen or there is heavy rain
* when I lower my pack down a rock face that it won't tear
*my gear is fully waterproofed with a pack cover and inner bag
* my first aid kit will be able to cope with a significant emergency
* I have adequate layers of warm clothing to cope with an unexpected bivy on the side of a mountain
* I have some elementary climbing gear if I need to descend down/up an unexpected steep slope
* I can cope if my GPS fails because I have a map and compass as backup
What is the point of sacrificing safety to save a few hundred grams weight?
