Safety issues in the garden-a little planning out can save a lot of time and energy. Found out the hard way, that just charging into a work situation with out thinking it out properly, is not productive, and can be dangerous. Not planning does cause you time, and loot-however, preventing injuries to your self, and family is the main focus, and top concern , especially when up in a tree trimming branches with a chain saw.
