Theres always the april curveball, when everything looks ready to pop. Southern and Central Ohio are going off. That random guy in the northern miracle microclimate is chirping ...then it drops 4" of snow or a random week of crippling frost mornings then Im out there collecting ticks, yelling at dryad saddles and wearing myself out.
Might just go by the calendar this year, last week of April and first week of May I always find 75% of whatever I find for morels.
