A 600lb grizzly...my, my.
"WHAT NO PICTURES!" By your own words I guess your story is worthless.
To a 15 foot gator, or even a ten foot gator, we wouldn't even be a snack.
Convict and I are Canucks. We don't have gators in Canada so a reptile as long as a car is quite an oddity to us (read as terror). While I do not suggest or recommend that if you see another large gator, leap out of the Jeep with a Kodak and yell smile, but to us any gator is scary and somewhat curious.
If either of us is ever in Florida jeepin', I hope we are fortunate enough to have some like you around to steer us clear of becoming something's lunch.
Oh yes, a 600lb grizzly...think of a very chubby "smokey" rummaging through the woods.
