I noticed you said ‘extra’ dry fall, not sure exactly what you mean but the dry fall isn’t the potential issue IMO. A drier fall typically allows for a more vibrant and longer lasting show. A dry summer could have impacts though. That said, there are a many variables. Timing is huge too and each little microclimate can have its own peak. Not sure when you went to Bear Mountain last year, or how their season was overall, but up here it was one of the better seasons in years. To be fair though, the previous few seasons sucked.
