We are pretty sure a real troll is living under an old bridge way out on a bike

trail, how can we be sure? He's a real troll? He challenges you whenever you try and cross "his" bridge...he's hunched over and looks really scary...a bunch of us think he really is a troll...should we just accept his challenge next time so he comes out where we can see him? We aren't afraid...well maybe a little...haha...suggestions??
