Hello Brandy,

Thank you for replying.  That is not a possibility.  I had a clear view of the fence on my approach to it and the posts were clearly visible to be secured in the block on the ground.  One section of the fence was at a slight angle to the other one and this is the one that magically opened  up.  I’m not mistaken.  It was late in the afternoon.  It was a blustery day so there were very few people around, just one or two dog walkers and it was too late for any official workers to be on duty.  On the second approach the angle between the two fence sections looked exactly the same as the first one but this time there was no gap for me to walk through.
