Does anybody have a recommendation for one of those travelling sprinklers? I just had my law re-seeded and right now I have a stationary 360 degree sprinkler that I have to move midway through the watering cycle to make sure I get full coverage because I have a spruce in the middle of my yard. I did some research and saw the Nelson Rain Train, that looks like it would be perfect to set up to go around the tree, but I see there have been mixed reviews on it. Anybody have any ideas?
