I went into the racetrack many times during the 70's and early 80's. Don't remember any length details although a Lance/Cherokee 6 with a little less than half fuel would lift 5 people back to MB. Take-off was downhill to the south and nearly always into 15+kts of headwind. The lake and the Pits have grown larger than I remember them.
I don't ever recall seeing anyone use the mainstraight as a runway but I only went there on race days. A number of drivers did fly themselves to the Island, a Black Bonanza and a White/Red C210 spring to mind.
I also had more birdstrikes there than at any other airstrip.
I can still make out the strips outlines on Google Earth.
