Another trip report: from BA to Mar de las Pampas on Saturday, taking the inland route via Chascomus on route 11, then 63 across to route 11/56. We had all our documentation, certificados de verano, but weren't checked once, not even entering Mar de las Pampas where there's a big checkpoint, but nobody checking anything. There are plenty of police out, cars parked under trees at the side of the road, but no activity. The most activity was at the multiple RADAR traps. The trip took just under 4.5 hours.
Hoping to see 84% eclipse here today, it will be windy but clear I hope. I figured there was too much risk driving further south, the zone of totality on the coast is in Rio Negro province.
