Nothing so crude. See my post #31.
I imagine that attending and VOTING at a precinct caucus near you (one for every 6 miles radius on average) was as easy as it was to go to my Washington state precinct caucus (1.5 miles away). Nothing complicated or tricky about it. No GOPe bending and folding and mutilating my ballot.
I saw a site on the Colorado election board where you type in your address and it shows you the details on when and where your precinct caucus is.
I went to mine, should them my driver’s license and gave them my precinct number and was pointed to a table. (About a dozen precincts were represented at the VFW Hall.)
Went to my district caucus after getting several email reminders to attend. Same thing - show them my ID, listen to some folks, some had obviously done this before and had fliers printed up about them and their views - then voted.
Making sure I filled in the circles with black ink was the most difficult. I’m a bit OCD.
