Kings Dominion here in Virginia has been analog for years, and the radio guys over there (from what I've heard) have tried multiple times to get them to go DMR, but the park won't do it because of the cost associated with the upgrade. I wouldn't be surprised if all of the other Cedar Fair parks are the same way. I don't think they understand the significant enhancement that a digital system would bring. Especially given how good the Motorola vocoders are at noise cancellation. In a noisy roller coaster or largely crowded environment, that noise reduction alone would bring a serious improvement to clarity of radio traffic. That, alongside the doubled capacity a TDMA enabled system would bring, should (I would think) be enough to convince the big guys to invest in a new system. However, not everyone sees the value in such a system and more than likely see the radios as a "as long as they work good enough" kind of deal, which is unfortunate.
