RV + the flyways
Bird migration along the flyways
Twice a year, millions of birds funnel down four great flyways across the country — sandhill cranes on the Platte, snow geese over Bosque del Apache, hawks streaming past Cape May. Most of the best vantage points are National Wildlife Refuges you can reach and often camp near in an RV. Here's where to point the rig by flyway, with each spot's window, flagship species, and an honest note on access. Migration timing shifts year to year with the weather.
