Narrative:

Followed another aircraft past hold thinking it was ILS hold line, even though I had been to runway before. There was no interference and error was only slight. I had frequently noticed aircraft doing same. Runway 15 used mainly takeoff only. The setup is very screwy on that runway for no apparent reason. Why is so much runway wasted? 9 out of 10 times, I see aircraft starting takeoff roll from unauthorized place.
