I collect a medallion for every national park I visit. So while Gateway Arch isn't a hiker's paradise with tons of trails, I grabbed a medallion nonetheless. There isn't a wide variety available for the park when internet searching, and this one looked the best to me.Medallion has a back adhesive (though it didn't seem as sticky as other medallions) and comes with three nails. Tap the nails slowly...even when you think you can start hitting a little harder, still tap slowly. I seem to always have one nail go awry. I haven't gone on any hikes since putting the medallion on my stick (COVID-19), so I can't attest to whether the paint chips easily or not. Overall, it seems to do just what a medallion should do - attach to a hiking stick fairly easily and look good.
