Great Points here !
Have MANY what you guys call Locals. I really doubt that ANY of them would actually chase someone, maybe one of the little guys, but not the ones that have been around for a 100 years. I have one that i have had sinse 1980. The only thing BAD about "locals" is they ALL are -10, but the numbers make up for that with ease.
Great point about NOT being the biggest one in the pond.
Locals i think are a MUST in sports gambling today, as many are slow to move numbers and some Always are moveing the number the "other" way as they dont usually move on AIR like others.
I myslef Always beat the number at one or two of the Local shops everyday. Over a course of time this will in fact make a difference in your bankroll.
