Moss Island in May?

This May I am thinking of doing a trip to Moss Island, most likely camping at Piseco-Powley Road then driving down on a Saturday to the Island. While all of Piseco-Powley Road wouldn’t be open in the spring, once the snow is gone, one can still drive as far north as the Potholers and the Hamilton County line.  I think it would be fascinating to see all of the wildflowers on the island during the spring time, as the last two times I’ve been to Little Falls it’s either been late August or mid-September.
