Well - if you want to use BP, don't give up yet. I think some of the guys on here continue to use it, and some swear by it - and they can help you find a source. I know one problem is that if you mail order it, you also have to pay a $20.00 Hazardous Materials fee. For that reason, I know most heavy BP users will order large quantities, since the HazMat fee is per shipment, not per pound (I think). Try sending aPM to Roundball, Cayugad or Taquahmenon(sp?) - I think all of them can help you.
ps - I live on the NW side, near Flushing.
