Davidmil,
I had to make two trips because at the time I bought it I was at the sportsmans show last year and there was no way in hell I was carrying a bow around with me all day[8D]. I also wasn't actually planning on buying one at that time either. Like I said, I'm sure I could have put it on, heck I work on my bow all the time, it's just that I felt safer letting someone with some experience installing it put it on, so I took it to Kinseys and let them do it.
