Years ago, sold a cue to guy in AZ. Went to poolroom, he was there but didn’t have his cue, said it was in car. Now it is summer time in Phoenix, temperature some place around 110 degrees (July). After a couple hours I leave, see his car, cue and shaft laying on dash of car in full sun, windows rolled up. Always remember it, can just think how that wood was reacting to being roasted, must have been 150 degrees on the dash.
