Small tight fields are a problem but are not an issue if you visualize a funnel with you being on the bottom of the spout. Instead of using the normal rectangular pattern to land use a spiral approach instead. I learned this long ago when I belonged to the "league of Silent Flight" flying gliders. You start from above flying a large descending circle decreasing in diameter on your way down. The last circle should place you about twenty feet above ground level and in a direction with the runway.
