The process I went through:
1) Arrive 5 minutes after polling place opens (turns out I was #37 to vote)
2) Get to table at head of line
3) Tell guy at table my name
4) He looks up name in book and I sign next to my name
5) He reads name and address to woman at table
6) That woman and another check for name in additional list (on green-bar paper) and then record name, address, and number 37 in written logs
7) Next woman in line hands me two-page ballot in plastic sleeve
8) I don't wait for a voting "booth" - there are only four - and I walk over to counter
9) I fill in little circles with a pencil (optical ballot)
10) Return ballot sheets in sleeve to woman who handed them to me
Total time: about 40 minutes (maybe 3 minutes spent voting)
At least it wasn't a punch-card ballot. Apparently 75% of Ohio (where I am) is still using punch-cards.
