Yea, when I lived in GA, we had both grass and asphalt runway, obviously it was a LOT easier to nick or break a prop on the asphalt. I now, unfortunately live in Illinois and our club just installed a 30x150ft mat type runway, the funny thing is that NOW the props can nick or cut the runway. We mainly laid it down for the electrics and small Nitro type planes. Sure makes it a LOT easier to take off than from the grass when you've got a small plane.
Anyway, good to see you can take some ribbing.
Happy flying!
