I understand where you are coming from .. but I think what Grant meant to say is that It's a wild animal and it belongs in the wild ..
I personally would of simply released it as soon as I knew that it was a milksnake .. keeping him even for an extra day could only make it worst for him...
I also doubt anybody told you to release it on the road.. read between the line .. release it in the area it was found that is safe .. ppl in this forum were simply trying to guide you - I doubt they apreciate the sarcasm..
With some luck the little guy will be fine
