If your skis are unusable, take them to the Eastern Regional Landfill. Or, try getting creative. Skis can be used for art projects. Consider posting them for free on Nextdoor or Facebook for artists to use. Or, if your skis are still functioning, bring them to a a local gear swap, thrift store, or sell at a local outdoor consignment shop like Tahoe Sports Hub or the Backcountry. You can also sell or give them away online with Facebook Marketplace, Ebay, or Craigslist. Find donation locations.
