I have used him for about three years now for most my part needs here at the stadium. There have been a couple times where he has really got me out of a pinch by providing a part last minute and even offering for someone to bring it down to me. I always know I will get a quick response on any request I have. Because of Jake we will continue to use LONG as out first option for parts here at the stadium.”Jeremiah
