Good or bad for the area?
Ironman puts on great, albeit expensive, events, that tend to have a huge draw. Ironman is also known to drop events without notice (e.g., Ironman Syrcause and many others). It's also rumored that Ironman buys competing events simply to shut them down and eradicate competition.
Here's to hoping Ironman is serious about the Finger Lakes, because it could be a nice boost for the area. Fingers crossed.
