Pomona is usually mineshaft , in November and February , but never seems to get those last few cars (top half) to -61 under. Last time we went , waited 4 days to get a run in.....cause it snowed , missed the mineshaft by 2 cars , went -64 under 1st rd. @ 150 , talk about sick , you got that right . Getting only 1 run is even sicker......
