This is only guide, not compursory. We (at least for myself) never charge for more than $0.10/KM. I only charged $5.00 to Royal National Park, and maximum $10.00 to Katoomba/Blackheath of Blue Mountains National Park, and all petrol charge to my car goes to public fund of our club (see #3 of Sydneyhiking Club http://www.freeoz.org/ibbs/thread-876952-1-2.html) in order to purchase 必用的地图,装备.
Couldn't agree more with you, V ban!!! 没有对与错, just diffirent opinion/interest. That's why I said early
"must have: certain level of EQ": certain intelligence know how to handle conflict and how to deal with difference. Conflict arises from this kind trip is a sure thing.
Detailling plan and budget, 只要在行程开始前大家认同即可 and stick to it.
