Realistically, the number of people able to march is diminished, but if unhoused and semi nomadic people are invited and willing to come along, suddenly we're a working class army. Multiple strikes shows them we can show up in greater numbers if we choose to.
I'm also assuming there will be Earth day marches that I won't know anything about until afterward, if you can get close to one, do. They're going to expect us in major city centers these days, and we really need everyone to just pick one.(and learn tactics and that most arrests are intentional and forewarned and de-arrest is often possible with enough eyes or bodies)
If you can't get to DC that day, get to your state capital in solidarity please. We need a show of numbers that actually scares them. We need people changing vacation plans for the election year. But that takes reminders and prep work
So consider this your reminder to take the day off or be prepared to play hooky one of these days of you have that ability
(if you can strategically risk a corp job, no call no show in massive numbers it becomes part of a nationwide protest and thus protected action)
