Glad to hear your first experience was a good one.
The only time I "touched" bottom was making the mistake that the safe side of the marker was the wider side. We had found a marker where that was not true. Fortunately we were at headway speed and raising the motor at the time of the touch as we realized our mistake.
I always check the chart until I get familiar with an area. Fortunately there are much fewer markers on the south half of the lake.

Some of the prettiest parts of the lake are where the markers are so don't avoid them for too long. Thank God they are here or it would be a scary ride.
