Much better photo of the group than mine JD, thanks for posting.
Definitely will come back the first week of Oct 2021 Tropp if that is when the color is at its best.
I read yesterday that the Holland "Tulip Time" festival is the 3rd largest festival in the U.S., drawing over a million visitors. So, no, have no interest in visiting the festival. But I would hope the week before or week after may still have a lot of blooms. I read the volunteers in the city plant over 850,000 bulbs just on city property. And I imagine homeowners probably plant double that in their yards. Must be spectacular!!!!! So I would hope there are some blooming in the "shoulder" period before or after the festival.
