I'm contemplating a number of options right now. Wherever we strike camp, my requirements are:
1. No more than four hours ride from Central London (say we average 10mph, that's 40 miles ruling out Days Lock unless we start from very West London)
2. Proper fires allowed. Andy and I will be demonstrating the proper bushcraft technique for starting a fire
3. Good, defensible position
4. Nobody's going to freak if we start shooting bowsanarrahs or lobbing tomahawks...
