I think a lot of it depends on your experience. A low time guy in a relatively new to him aircraft, yes, as av8r3400 said, suicide!!! For a well experienced pilot that knows his plane it is maybe do-able.
I had a 1,000 foot strip in the thick woods with tall trees on both ends and I was landing/take-off a Champ in and out of it. Granted when heavy with a passenger it could get quite exciting if the winds weren't good.
Another thing you have to think about is the neighbors, will they have a pi$$ing maych with you when you are on approach or taking off over their property? I am very lucky in this aspect since my land is entirely surrounded with state forest. But guess what? I still had someone complaining that I was flying low. Had a deputy drive up and I had to explain that I need to fly low in order to land.
