I saw lots of acorns early in the year. The seem to start dropping back at the end of august here in Maine and New Hampshire. I too am acustom to the sound of falling mast but not this year. I 'm not seeing very many on the ground either. I guess what has fallen was eaten up quickly or gathered and stored away by the squirlles.
Keep doing what you're doing and in time you'll connect with your buck.
Congrats on the does though!
