Very nice! Remember the acronym “OCOKA.”
-Observation
-Cover and concealment
-Obstacles
-Key terrain features
-Avenues of approach
With that in mind, think about what you’d look for if you were the cop. Litter is probably the biggest give-away, but solid colors, straight lines, unnatural colors and unnatural breaks in vegetation are other things they look for. Also, try to keep your plants out of direct line of sight from any of the possible avenues of approach. You did very well planting them in the midst of other vegetation. In addition to that, LST them down so they’re never more than 2-3 feet (60-100cm) tall, or whatever height it takes to keep them from silhouetting themselves against a background. If you can’t avoid silhouetting them, make sure they’re against a background of other vegetation.
