Keep looking everywhere and Keep a good look out for the Poles. They usually have the wires attached to them
Good to know the aircraft's limitation, however, know your own as well. Every day is different and so is the weather as you would know. Some days you can fly lower than others. Considerations are the wind, sun and visibilty to name a few.
Like you say, always look for a good landing spot along the way.
Not sure how low your low flying is? Had a station manager that used to like flying high, 300 feet.
They were fun days.
My two cents worth
