Where did the OBS occur?

[mcrowder]

Ask yourself this - is the runner still obstructed while making that first step from first to 2nd. Most of the time in the sitch described, the answer is yes - thus, they were obstructed while between home and first, and they were STILL obstructed while between first and second. So in most cases, they cannot be put out between 1st and 2nd either.
