I didn't change my stroke, but I just hit the birdie putt way too hard.
I bogey that hole, birdie the par 5 and shot 5 under. I love the course, and I figured no matter how bad I felt, I could get around and have a decent score.
Other than those few holes, I had a lot of birdie chances. To be five under, blow four strokes, then get five strokes back is a pretty good way to end the day.
