Well, after about 30 hours past getting my wet Private License I took my dad up flying. Went to plum island (2B2) and it's a 2100' strip. Well, it was early in the day at that point. The sun had been up for about 3 hours and it had warmed about 15 deg. My TOLD was at 1900' for the takeoff to clear a 50' obstacle. Well, on the west side of the field there are 70' trees. I intended to do a touch and go, but once we touched, we didn't have enough room for the go. So we taxied back and took off. The trees brushed the underside of the warrior.
So what had I forgotten? Sea breeze. See kids, in the daytime you get winds off the ocean. Plum island is about 3 miles inland and has a beach on the east side. So while Bedford (KBED) was taking off to the west, I should have taken off to the east, with wind, over the beach and avoiding the trees.
I still tell that story to my students. I still had plenty in my luck bag and not enough in my experience bag.
