For two months last winter I watched the Corp of Engineers dredging a new canal and rebuilding the beach at Padre Island just accross the road from our condo. They work 24/7 around the clock, rain or shine and they are amazing.
Fill trucks were backing out on a temporary road a 100 feet from shore dropping gravel, all day, all night. If you own the gravel pit, your going to be very happy.
