Ah, so the lawn guy is still going there. That does help. With all the trees in your yard, it would be almost impossible for the ducks to find their goodies in the thick blanket of leaves.
A lot of times the smaller businesses are better to deal with. They know they need to put in a little more effort to attract customers and you get better service. It sounds like your tree guys have succeeded with that since the waiting list is long. :-)
I’ve used them twice before and been very pleased with the service.
The biggest one never got back to me; the second’s service after the tree came down and the stump was supposed to be removed left a lot to be desired. So Paul’s Trees got my call several years ago and each job has gone well.
