Im assuming you mean the one in the middle? He was the biggest one I saw all summer for sure! How do you tell the sex? Here's a couple more pictures that I snapped of him.
I took a pick of a rattler with 13 rattles a few yrs ago little easier then judging rings on a ram lol.monster rattler
You bet he was about a mile off the suffield border. Seen a few bulls off the base but this one was something else we jumped him around 50-60 yrds and by the time I pulled my camera out and chased him down with the camera he was around 150 yrds looking at me and then kept heading for the border.
