A flexible marker device comprises a marker body having a bottom end and a top end, and a base for supporting the marker body. The base has an aperture in a center portion thereof and a groove extending about the aperture in an upper surface of the base. The bottom end of the marker body is at least partially disposed within the groove. A cured material, preferably polyurethane, is disposed in the groove to thereby secure the marker body to the base.

What is claimed is: 1. A flexible marker device, comprising: a marker body comprising a flexible skeleton and a flexible cover disposed over said skeleton, the marker body having a bottom end and a top end; and a base for supporting said marker body, said base having an aperture in a center portion

What is claimed is: 1. A flexible marker device, comprising: a marker body comprising a flexible skeleton and a flexible cover disposed over said skeleton, the marker body having a bottom end and a top end; and a base for supporting said marker body, said base having an aperture in a center portion thereof and a groove extending about said aperture in an upper surface of the base; the bottom end of said flexible skeleton being at least partially disposed within said groove; and a cured material also disposed in said groove to thereby secure said flexible skeleton to said base. 2. The flexible marker device as recited in claim 1, wherein said flexible skeleton comprises a length of flexible material formed in a coil and thus comprising a spring, including a bottom coil which comprises the bottom end of said flexible skeleton which is at least partially disposed within said groove. 3. The flexible marker device as recited in claim 2, wherein said flexible cover comprises a mesh material having a plurality of small apertures therein, a bottom portion of said mesh material also extending downwardly into said groove. 4. The flexible marker device as recited in claim 3, wherein some of the cured material extends through the mesh material, thus assisting in securing the marker body to the base. 5. The flexible marker device as recited in claim 1, wherein said groove is shaped so that an upper portion thereof is narrower than a lower portion thereof, whereby portions of said base which define said groove converge toward one another in an upward direction. 6. The flexible marker device as recited in claim 5, wherein said bottom end of said marker body which is disposed within said groove is at least partially constrained from exiting the groove by said converging portions of said base. 7. The flexible marker device as recited in claim 5, wherein said groove is defined in part by a wedge-shaped portion of the base which tapers inwardly in an upward direction, the bottom end of the marker body which is disposed within said groove being disposed against said wedge-shaped portion of the base so that the base portion constrains the bottom end of the marker body from exiting the groove. 8. The flexible marker device as recited in claim 7, wherein said groove is further defined by an overhanging portion of the base. 9. The flexible marker device as recited in claim 1, wherein said cured material comprises polyurethane. 10. The flexible marker device as recited in claim 1, wherein said base comprises rubber. 11. The flexible marker device as recited in claim 1, wherein said cured material substantially fills said groove.
