Monarch PEAK Migration

Date: 09/20/2018

Number: 27

Driving west I-80 on 9-20-18, began to notice monarchs just west of Grand Island, Nebraska. Counted 27 in 1 minute! Went to MonarchWatch website, saw that area is on the fall flyway. Looked up peak migration dates: 8-20 Sept. So now, trying to figure out how WIDE the flyway is during peak migration, in miles, so I can quantify the numbers a bit. I know my data would be a gross estimate, but on a long drive, what else is there to but speculate?! If you know the width even approximately, please respond, and if you can, include my note in the response?!
Thank you so much!
