be cool to see a defence vid we see loads on weapons but how do youi defend your house/farm/car/bike/feet/hands/head in a place where it kill be killed. car maybe electric (as long solar charge could last longer than petrol???? but can make petrol and deisil so it wouldnt run out as in films, you can run a petrol car on booze) feet as lots broken stuff on ground and leg traps would be used. hands falling onto glass and stuff bad, push bike quiet easy maintain but not much armour
