Definitely have those meals that will live in memory forever. Breakfast burritos in Austin, tacos in Costa Maya, mufungo in San Juan. Best part of traveling!

All of this is in addition to calling your representatives at the local, state, and federal level. Calls work best and you put them there so make them hear you.

For my people worried about public lands start searching or walk into your local park/forest/historic site and volunteer. Many have trail clubs, friends of groups, etc that fundraise and do maintenance on the property. You can at least have a bag to put trash you find in while you hike.
