I don't believe that the locations and dates have a lot to do with KCBS. It appears to be more of logistics about going from one contest to the next, week after week. Sam's along with MMA pick locations and dates and then check for other KCBS contests in the area since it is a KCBS sanctioned contest. Most of the time, other sanctioning bodies do not even consider what others are doing as there are no established communications except via phone calls after the fact.
If you feel strongly enough about the scheduling, then contact the folks who are in charge, MMA, and discuss it with them. Last year, there was a problem with one of the locations chosen that only the local people were aware of. This information was communicated to MMA and they, in discussions with Sam's, made a change.
Bringing it up on a forum is well and good and allows you to vent and gather addition support for your position but, it won't acheive the desired results, only direct communications with the actual people doing the schedule can accomplish change.
