Is there anyway to get a patch of bubbles out of the polyurethane coating of my hardwood floor?

I dont' want to just put another coat of poly down, this was coat #3. 1200 sq feet of 60 year old red oak hard wood. No matter how careful I am, I have had at least one "patch" of bubbles somewhere on the floor on each coat. The bubbles are not all of over the floor! I THANK GOD for that! :) I don't want to put ANOTHER coat down. Anyway to get the bubbles out? The poly is dry, but not cured.Soft in the spot where the bubbles are, but not tacky on top. I thought of getting my hair dryer and heating it up a little to see if they would dissappate a little. Pobably an assanine idea. Maybe they won't be noticable once the floor is dryier? I've noticed in the past on a different project I did, there was some puddling, with very noticable lap mark. But as the poly cured more, the lapmark/puddle mark seemed to dissappear. So tell me any ideas. I"m a DIY...but wonder how the pro's deal with bubbles.
