Paying 120 on a 60 hole board

I've got some cool boards that only have 60 holes (30 up one side). After having a few drinks, I've found it hard to peg accurately. Any suggestions on how to play to 120 on a board with only 60 holes per player?

Hi, Not an answer, sorry. The same question asked differently. I am new to Cribbage, I have a 60 hole board. Does it ever happen that you get confused if on the first time round or the second - say 25 not 75. Maybe after a few drinks, late night or just after rescuing the roast.
