to be honest an im gonna sound like a dick here roll over and take the beating and leave it at that . if it happens again then seek police help.
its happened to me many many times so noones to go " you dont know shit about this "
my point is in reality nothings going to happen , you spend a few days plotting but you'd be very stupid to carry any of it out . you could carry a knife , but
a. only if you knew how to use it
and
b. only if you were willing to use it and face the consequences of the injuries involved .
the plotting is normal its just a way of venting anger it happens almost every time , let the bruises go and let the injuries heal and if you see them again just ride past and ignore them .
if you had any sense you'd ride in a group from now , but dont let it get to you go about things as usual but stick in a group and hopefully stay safe .
edit : you called them packi's sounds like you deserved it
