If rakes have a integral 'support' for the handle (its a disc on ours) then I really don't see an issue with them being left in the bunker - in the bottom, parallel to the long axis of the bunker. Due to the head and the support, the rake has minimal contact with the sand, won't iimpede the ball, and would rarely (very rarely) stop a ball rolling down a gradient. Admit i can see an issue with small pot bunkers though .
