I'd like to think that if I ever made a mistake (wrong frequency, etc),
someone would cut me some slack.

Exactly. Once I punched up the wrong frequency at my own field... I was
looking all around as I taxied and made my calls. I saw and heard no one
else in the pattern or on the field as I took the runway and departed.
It wasn't until I was airborne and still hearing silence that I took a
close look at the radio and noticed it was on the wrong frequency! DOH!

If there is no activity on the field nowadays I call up UNICOM for a radio
check.
