..as for tasks, I would keep it simple. In a recent "
dress rehearsal", I practiced the really basic things e.g. -
finding a good spot (more difficult than you think);
pitching up (in my case tarp and hammock); and making your site comfortable
practicing fire prep (not necessarily fire starting, but at least selecting and gathering wood);
practicing making basic utensils (billy stand and support - even though I didn't use it on the ocassion)
actually cooking (ya gotta eat)
setting up sleep arrangments (I'd do that prior to actually sleeping - to iron out any problems that would be difficult to solve in the dark)
thinking through contingency plan (what if your tent set light - what would you do?)
try your hand at a simple spoon or eating utensil, and actually use it.
These are simple tasks. Too many and you'll exhaust yourself and get put off. The most imprtant thing is to relax and enjoy yourself!!
