do garter snakes get bigger in the wild?

[zooplan]

The pictured snake lokks bigger than it is, because she´s angry and has pumped up herself to fend those predator called camera.
Weight is more expressive than length. Ribbon snakes get more than 3ft too but reaching only about 150-200 gramm. Easterns can get more than 300 gramm with the same length.
Allways talking about females because males will stay smaller and skinner.
