I'm well aware it's a not a good idea to leave bowling balls in your garage, trunk of your car, etc. Anyway I usually keep two old bowling balls in my trunk during the winter as weights or as a backup if I feel like practicing or something. As you know it's been quite cold lately on the east coast, temps ranging from the low teens to low 20's as of late. My question here is what is the lowest temperature a bowling ball can take if there is such a thing before it would crack or destroy the ball? Also, is it just as bad leaving your plastic spare ball in the trunk as it would a resin or would the resin ball be more adversely effected? Just a thought that came to mind during this super deep freeze happening along my neck of the woods. Thanks and any comments/thoughts appreciated!

If a ball has a core of any kind I figure its chances of failure is much higher. The weather with those kinds of extremes will cause shrinking and swelling and can easily cause the core to separate from the ball, cracks, and other problems
