What do you do with your bow in the offseason? Put it in a case (away from sunlight, scents, etc.) or hang it on your bow rack, which can be exposed to the elements?

I put mine in my hard case under the bed.

There is no such thing as an 'offseason.' My bows are all being shot, year round. I bow hunt through bow season and on through gun season. I bowhunt small game. I bowhunt spring turkey. I bowfish for carp in the spring and gar in the summer. Fill that in with 3D once or twice a week and the occasional field archery round and it's time to start tuning up for bow season again.

Really and truly, I don't know anything about storing bows because I never store my bows.
