Right you are, Koz - I wouldn't want to stand between either of the two larger North American Ursus members - grizzlies or polar, and a package of Twinkies..or their cubs.
I-swear-to-god-True-Story:
The Year - 1964. Summertime. Family camping vacation across the country. Second of three nights in Yellowstone. I share tent with younger twin brother and sister (I'm 11, they're 10)...wake up feeling cool breeze early in the morning. Brother is sitting up in tent, looking rather pale...
"what's going on", says James, sleepily...
"Didn't you wake up?" brother chatters.
"No....whattady mean?"
He pointed behind me - the side of the tent, about 6 inches from where my head had just been, was ripped to about a 20" opening.
"about ten minutes ago a bear just stuck its claws through the tent there and stuck it's head in, sniffed around, and then left!"
Musta missed my cheekbone by about 3 inches. Slept right through it.
Mom and Dad were freaked out..
No harm, no foul, I say.
