DW does have a lot more mainstream celebrity status, largely due to the fact that there is still a lot of love out there for Dolly Parton. The park is also the biggest in the chain, and it does showcase the best of the Herschend's latest attractions such as Thunderhead and Mystery Mine, as well as some awesome new shows.
Back in 2001, DW was very much over-looked, while SDC was being pushed non-stop by HFEC, if I recall correctly. Once SDC gets back to installing big new rides, the cycle will probably push back in its direction for awhile. It's not like the chain is playing favorites though, it's just a fact that DW has more to show off right now, as well as more potential for growth and profit.
Anyway, back on topic, has anything else happened around the train tracks? Was that work earlier just for replacing ties, or are they doing more? Also, what's the hole status? Anything going on around there?
