WHEN TO GO / EVIDENCE REGISTER

Seasonal detail, without false precision.

A runoff program, a winter migration and a summer insect opportunity are different kinds of seasonal evidence. The scope of each reference stays visible.

Dates below are broad source references—not weather forecasts, guaranteed availability, legal opening dates or catch probabilities. A partial month does not become a full-month promise.

What remains unknown.

The remaining trip guides have qualitative seasonal discussion, but this edition does not establish a dependable month range for them. The planner does not translate missing evidence into a confident recommendation.
