Used that on some private even not expensive, visible, and say what it need... if you meet some compact trees sections or want to be more carefull of you you can also tie 2 trees together every 15 feets ...
exemple: |--tie----|#|# |#| |###|--tie----| |###|##|------|##|### |### | ----tie---\
people can't miss it ! it last long and it do not damage to anything if you use your head a little...
+ It will be easier for you to locate sections that need to be ''refresh'' after few years. To keep my tapes steady I tell before each game that If you see them you are already too close from them ... it avoid most of gun fight where bbs could rip them ... but shit happen sometime however 3 inch wide are enought to sustain many shots ...
+ It can help if you do have insurances for the events ... (don't know why but it might be more ''official warning''
