Narrative:

Following a normal approach to landing at a back country airstrip; and during the rollout phase it appears as though the brakes were being applied by the right seat passenger. The wheel landing (which I have done literally 1;000's of times) seemed normal until the point at which the tail should have started to settle. The tail did not settle as expected and at this point the aircraft began a very gradual left turn and with the tail rising. The prop struck the ground. There were no injuries. The aircraft had only two front seat occupants; was full of fuel and any application of brakes at that time is not something that one should do. Having had lots of experience in this aircraft I am quite comfortable that a) somebody had their feet on the brake(s) & B) I am relatively sure it was not me.
