Johnny,
The flash is immaterial. The rattlesnake can strike accurately in complete darkness due to the infrared sensing capabilities of the 'pits' which give name to the class it belongs to: pit vipers.
It's position is consistent with timber rattlers I've seen in the daytime that are trying to rapidly change positions to avoid a larger animal,i.e, me. Looks to me as if the snake was caught by the flash trying to get out of the way of the deer.
Allison is certainly not above trying to pull my leg completely off not just a 'leeetle' bit.
However, I'm having to help her with the computer literacy. Given my relatively sparse computer literacy, I don't think she's got the ability to photoshop something. It's certainly possible she's got access to a stuffed snake even though I've never seen a mounted rattlesnake that wasn't coiled.
Woman's a bit unusual even for us hunters. Her favorite hunting picture of a buck she's killed was taken just after she finished gralloching it. She's covered in blood to the point that I thought her hunting buds had drenched her in deer blood. When I asked her about it, she replied that she got that bloody while gutting the deer-and munching on its heart
To look at her at work or in town, you'd think she was more at home at the theatre or such. Get to talking to her and you shortly realize that this is a rural farm gal-and the rural goes deep.
As far as size goes, timber rattlers aren't huge rattlesnakes. Four and a half feet is a big one.
