Remember that gravity only affects the arrow on the horizontal component. If you use a laser range finder from your stand height and range the base of the landmarks around you(where you would expect to shoot) you will get a reading slightly farther than the horizontal component because you are shooting along the hypotenuse of the triangle. If you are going to use a laser rangefinder, range the landmarks as close to the elevation you are at as you can. That way you are only getting the horizontal component and you won't be shooting high. This may be getting too techy sounding and take some of the fun out of it, but it is info that should be useful in the future.
