Late Night Walk.

I was just out for my late night walk and had a bit of a surprise. I heard gulls at one point along the way. I've heard other birds flying at night, such as geese, but to the best of my knowledge I haven't heard gulls before. It would be interesting to know how they navigate at night. I also picked 30 cents worth of empty bottles for my recycling pile that were sitting in the street. Hopefully I'll have the energy to go out for another late night walk tomorrow, as I can use the exercise.
