Rhubarb is almost ready for a first picking (which is sad 'cos I go away

Our rhubarb looks pretty much ready to pick.
How does one know when it's 'ok' to pick?
Iirc, it gets poisonous when it's older, so a too early picking is ok other
than potentially damaging to the plant - nothing to stop me making an early
crumble tonight?
