on the cusp

a week of sunshine and 80 degree temps was all that was needed to trigger an explosion of blooming plants. what is the seasonal event that says “summer is here” for you?  meteorological summer begins june 1. astronomical summer begins on the solstice, june 21. my local naturalist guru i rely on heavily (larry weber) says that spring ends and summer begins, for him, when the open field flowers start to outnumber the woodland wildflowers. by that definition, i would say we are right on the cusp of summer here in minnesota.
