When a league is dissolved it doesn't mean it can't return. Long before we moved where my kids grew up the town left LL. They had their own independent program. It became part of Ripken during my board tenure. While a lot of town kids played Ripken the town was divided among three bordering LLs. My son played for one of the LLs when he was eleven and twelve.
Back when he was seven we (the town indy program) attempted to rejoin LL. The first problem was two of the three LLs that inherited part of our town refused to surrender the territory. The other issue was in order to place LL under our youth sports organization (baseball, softball, basketball, football, soccer, field hockey, street hockey) we would have had to rewrite the charter to comply with LL.
From having been involved in both youth environments I would say Ripken is a much easier organization to deal with in terms of running your league. The problem with Ripken is the lack of rules when the wrong people take charge locally. It's why we left for LL. The allure of LL is the all star run if your program is competitive. My son's LL all star teams played into August both years.
