I flew my Maule MX-7-180 into and out of Basin Harbor Club’s grass strip in 2007. I landed there in the afternoon on a Fall day with a cool temperature. I took off in the morning with a cool temperature. Density altitude wasn’t a factor since the elevation is near sea level. The grass is kept mowed so drag shouldn’t have been a problem. The runway is long and wide (for a Maule). However, there were thousands of seagulls on the runway. The guy mowing the grass scared them away long enough for me to take off but they came right back afterward.
