To keep with the 'things we've found in different times of the year/seasons of the year', (if that's what we are doing now). I was several hours from home, and took my mountain bike because I was going to another area the next day that had 'some trails'. So I saw a really short trail that had some bridges like this. I figured, what the heck, and threw my stuff on, and took off to explore. I found a rather large turtle on the end of one of the bridges. He was a stout looking fellow, and had an out of scale attitude. He turned to face me as I got near him. He also hissed at me, and I've had cats, and hissing at me is a deal breaker. I slowly approached him (I assume it was a he) and he took a decidedly 'macho' pose. He was going to 'take it to me'. Well, okay...
So I rolled towards him, and he reared up, and started looking really aggressive. Me, on a 29" mountain bike, full gear, and him, well not. As I rolled closer, he started coming at me, and bit my tire! I was so frightened (not really), but he wasn't giving any ground. He was determined to keep me at bay. I have to give him kudos for having the balls to do that, I was impressed. So I backed off, found a stick, and let him attack me through the stick as a proxy. Oh, yeah, he bit, HARD. I was actually able to lift him up, and move him off the briddge to save other people from his Napoleon Complex. Such bravado from such a small, and ferocious entity. I really was impressed. Do your worst!!!
