I usually venture away from the crowds....
I do the same thing, especially when you get guys who drive to their holes instead of walking. I feel they are driving more fish away then they catch. I try to be as quiet as possible on the ice and I think it pays off. It's very similar to deer hunting during the gun season. I try to get back in away from where I know other hunters are likely to be and let them push the deer to me! The same holds true with ice fishing... besides I like my peace and quiet.
I learned a lesson the hard way also about leaving your catch on the ice for others to see. Yeah it's nice to show off that lunker that you caught, but I had one guy on a snowmobile pull up to see what was going on and when he saw my fish he drove about 50ft away and started drilling holes!
So now my fish get buried in the snow right next to my shack, or go in a box on my sled.
