We construct a space for which the canonical homomorphism from the fundamental group to the first \v{C}ech homotopy group is not injective, although it has all of the following properties: (1) is a 2-manifold with connected non-compact boundary; (2) is connected and locally path connected; (3) is strongly homotopically Hausdorff; (4) is homotopically path Hausdorff; (5) is 1-UV; (6) admits a simply connected generalized covering space with monodromies between fibers that have discrete graphs; (7) naturally injects into the inverse limit of finitely generated free monoids otherwise associated with the Hawaiian Earring; (8) is locally free.
