I have just resumed camping after a long absence. Out of the 2 camping weekends I have gone to I have not found any rocks large enough to pound a difficult stake in. Luckily the Boyscout tents use the thin metal pegs which are easily pushed in. And both campsites suffered from soil that was way too soft (pegs tended to pull out).

And all the wood was quite rotten or soft, no good for pounding.
