stopped hunting west side "combat zone release sites" years ago... no room, too many people.... very dangerous situations created on release days, those 0800 march in formation hunts are not bird hunting.... 
The problem is if you only have an upland dog on the west side you better like grouse in the absence of release sites. The east side is great, but as a west sider it also takes forever to get anywhere with decent hunting there. Not optimal for those with a job, a budget, and young kids.
