Well, at least it was in a case!

Here in the NE our archery seasons can see temps from 70F down to 0F with rain, snow & sleet thrown in; I've had my bow in hand through all of it.

I do understand your concerns but would think if you waxed the string before storage & it still looks fresh you should be fine.

Your rubber bits-silencers,etc may be tired.

Modern bows are pretty tough stuff.

If truly in doubt, see what your local shop thinks.
