Thanks to everyone for your ideas and comments. Accepted a bid to open up the three trees in that area. Great!
Sadly, infuriating occurance. Doorbell rings, there stands a pool/landscape guy. Rearward neighbor told him our pool has a leak and needs repair. Clue, standing in the neighbor's front yard anyone can clearly see that there is no more pond. Three weeks ago I even told the neighbor exactly what we are doing. The terribly whatever neighbor told the pool/landscaper the the leak in our pool is flooding his yard. Cathy told me to chill so I will remain a nice guy.
