Years ago I used to hunt ducks and for that I purchased the federal duck stamp. It's a tax that is used to improve wetlands so it helps ducks and all other creatures in the wetland. I no longer hunt ducks but I still buy the duck stamp. If they could start such a fund that would be used to improve all the hiking trails I would be willing to purchase a hiking stamp. This would only truly work if it was required for all. You want to hike the Appalachian Trail? You would be required to purchase a AT stamp. Would you support such a tax?
