You said you wanted opinions, so...

You bowhunted in the rain.

By doing this, you eliminate the one way to follow a shot deer (the blood trail). So now you have to wander around blindly and hope you stumble upon it. As it wasn' t a perfect shot, the deer is likely to have gone a decent distance, and holed up in some thick cover where it' s hard to see. You might find it, and you might not.

Had you shot this deer on a dry day, your odds would be far, far greater of recovering this deer. And if you hunted this spot a day or several days later, there is a good chance the deer would have given you a shot eventually- so hunting in the rain *may* have cost you this deer, and may have caused the deer to be raccoon and fox food instead of gracing your table. I don' t blame your shot- no one makes a perfect shot every time. I haven' t, and anyone who hunts long enough has been there. This is why many won' t hunt in the rain.

It is your responsibility as a hunter to search as hard and long as you possibly can. Do that, and you may be rewarded by finding this deer in fine shape. I hope you do, and I hope you draw a lesson from the experience no matter what happens.

Good luck.
