  Almost Fall   Signs the that summer is slowly giving way to autumn

     fallen birch leaf  changing to fall colors                                                                    acorn on forest floor -start of  harvest for woodland creatures                        mushrooms emerging        

        Nearly Fall
by Michael Chanteur

Late summer gives us a hint
Of the color that is to come.
It shows up as a red or orange leaf
Here and there.
Asters starting to bloom
And summer flowers fading.
Despite a persistent daisy or two,
The signs are very clear.

Under a Rock - below are some creatures I found on my property in central Pennsylvania lifting up rocks.

garter snake(Thamnophis  sirtalis )                                     ring-necked snake(Diadophis punctatus) small, but actually slightly venomous                 brown snake (Storeria dekayi)
