Six Flags Darien Lake (SFDL) Discussion Thread in Theme Parks, Roller Coasters, & Donkeys! Posted May 13, 2020 The fact that the park is in Genesee County could be super beneficial to getting the park back open sooner. Honestly I was somewhat surprised that they labeled it as the Finger Lakes region, given its close ties with WNY. If the park was in Erie County, the wait would be so much higher for a park opening, if at all. Here’s to hoping that the Phase 1 numbers don’t get nasty, and we can progress to an opening of some sorts!
