Landing on turf! I hadn't done it since primary training, but my first CFI had me do quite a bit of TOL practice on "unimproved" surfaces in an old, beat-up, barely airworthy 150 (after soloing I decided it really WAS unairworthy and switched FBOs, sadly it was the only airplane he had reliable access to). I remember Merillat (34G) which advertised fuel 24/7 but I never saw the pumps, and Indian Creek Ranch (56G?) a deserted little strip out in the middle of nowhere about a couple miles from Lake Huron. We also landed a number of times on 18/36 at New Haven (57D, now Ray Community) which is part paved but very narrow, as in 25 feet, and part bumpy turf. I really enjoyed those flights, and Greg was a great teacher. But after getting my private I never dared again to go into one of those places, until a couple of weeks ago I followed another pilot and landed on 18 at Owosso (KRNP). I follow Bruce's rule of thumb and only land on grass if I've walked the runway or talked to someone who knows the current conditions. But that was a good decision that day (for me, maybe not the other pilot!) since the wind was straight out of the south and pretty stiff, and the paved runway is 10/28. I'd forgotten how easy and smooth landing on grass was, without the rising air coming off of hot pavement.
I'd love to go back to Indian Creek someday, but the description in the Michigan Airport Directory is a little daunting: rwy 18-36 & 9-27 surf. rough with ireg. mowing. It's also unattended. They do give a number to call for conditions though, so maybe I'll give it a try someday.
