Free entry to all US National Parks today 24th September

Thanks @Vanessa_A for getting the word out about this. The National Park Service in the US actually has several free days throughout the year.

Just a reminder: Many of the most popular parks now require a timed entry permit, as there are too many people flocking to them and clogging the roads and trails. So do check on the particular park you’d like to visit, even if over one of the free days, to ensure you’ll be able to enter or drive through it.
