for those that want to really understand the dynamics of a bear charge with out getting in the ring with one i would suggest going to the wreaking yard in the worst town around where they have a couple Rottweiler's guarding.
wait till dark and crawl over the fence make some noise and experience the rush.
during said rush practice your fast draw and precision placement shooting. might be close to the actual thing.
then again maybe not.

the consolidation of the states into one vast republic, sure to be aggressive abroad and despotic at home, will be the certain precursor of that ruin which has overwhelmed all those that have preceded. Robert E Lee
