I was out practicing between 06C and KDPA today under calm or very weak winds from the SSW. The airport asks pilots to use runway 29 in calm winds or direct crosswinds, for noise abatement. As I announced my entry into left downwind 29, a "blue RV" came on CTAF announcing a fly over the field to enter left downwind for 11. I informed him that the airport was using 29 at the time. He came back and said, "well, the winds are favoring 11". The AWOS at the time was broadcasting 22004KT. Eventually, the "blue RV" announced left base 11, then final 11, then exiting the "active" after he landed. I had him in sight and I ended up extending my left downwind for 29, just to be safe. Not a big deal. I haven't checked my GoPros yet, but I think I have the incident recorded. I also took a photo of the tail number of the "blue RV" after I landed. I was annoyed at the time. This guy comes in, spins the airport to his convenience, and disregards the effort for noise abatement and being a good neighbor. And all that for what? To make it to Pilot Pete's happy hour?
