HAVE: Swamp Chestnut Oak Acorns/WANTED: Burr Oak Acorns

I just collected some of the big acorns for Swamp Chestnut Oaks (Quercus michauxii) from some nearby hiking trails and have lots to give out. I would like to trade some of these for some burr oak acorns, or chinkapin oak acorns. I also have lots of large white oak acorns from my yard.

I also forgot to add that I'm looking for some Mexican Buckeye seeds.

Thanks!
