who stole my pumpkin?

Last week I took the x large pumpkin in front of my house to the woods in back.From there I rolled it down a hill towards a pond.The pond has a steep hill completely surrounding it.The walking is tough back there with downed timber and blue berry bushes,the pumpkin had no handle.I had to carry it with both hands underneath.Today I walked the dog back there and the pumpkin was gone.We searched the area around the pond and concentrically outward for about 150 yards.Not a scrap of highly visual orange rind ,a seed,nothing.It could not have been rolled uphill and carrying it any distance would have been difficult for a strong adult male. Late today I put two smaller pumpkins out in the same spot,it was and is snowing.At dark they were both still there.These do have long handles.At daybreak I will check them.If they are gone.I will brush thru the snow.We have several deer here nearly every day and probably every night including a 4 point buck and an 8 point buck.They had tried to eat the pumpkin before,knocking it off it's perch and could only put nicks in it with their front teeth.Earlier in the year we had 4 bears here regularly a young femalee and 2 cubs.Plus a very large male.No sign of them recently.So who or what got my pumpkin!Going to deer hunt again this year for the first time in at least twenty years with a borrowed 30/30 and have an awesome buck,twice the size of the eight pointer located probably tough as shoe leather,stew meat!Maybe some chili and soup!
