1. A snowboard anchoring system adapted for stabilizing a snowboard while a user attaches a user footwear at a snowboard binding affixed to the snowboard, said system comprising: an anchoring stake not associated with the snowboard and readily manipulable by the user; wherein said stake includes a snow packer shelf and a shaft with retainer segments therealong; and an anchoring line securable at one of the footwear and the binding for selective engagement with said stake when snowboard stabilization is desired.
2. The system of claim 1 further comprising a safety line having a clip at one end for association with the footwear and attachable at an opposite end to said anchoring stake.
3. The system of claim 1 further comprising a retainer having a retractable cord extendable therefrom, said cord attachable to said stake.
4. The system of claim 1 wherein said anchoring stake includes a handle.
5. The system of claim 1 wherein said anchoring line includes a single strand of durable cord secured at its ends.
6. A snowboard anchoring system adapted for stabilizing a snowboard while a user attaches a user footwear at a snowboard binding affixed to the snowboard, said system comprising: an anchoring stake not associated with the snowboard and having an attachment thereat; a retainer having a housing securable adjacent to the footwear, a retractable cord maintained in said housing and selectively extendable therefrom and retractable thereinto by a user, said cord attachable at said stake attachment; an anchoring line including first and second loops, said first loop securable at one of the footwear and the binding and said second loop for selective engagement by said stake when snowboard stabilization is desired; and a safety line attachable at one end with the footwear and attachable at an opposite end to said anchoring stake attachment.
7. The system of claim 6 wherein said attachment at said anchoring stake is a ring affixed to said stake.
8. The system of claim 6 wherein said housing of said retainer includes a footwear mounting clip.
9. The system of claim 6 wherein said stake includes a snow packer shelf and retainer segments below said shelf to better assure stake retention once implanted in snow.
10. The system of claim 6 wherein said first loop of said anchoring line is securable at the binding and said second loop is freely manipulable to positions spaced from the binding.
11. The system of claim 6 wherein said safety line and said cord both include clips releasably engagable at said stake attachment.
12. The system of claim 6 wherein loops of said anchoring line are formed by intermediate securement of an endless strand.
13. A snowboard anchoring method for selective stabilization of a snowboard while a user is standing thereupon comprising the steps of: securing a line at one of a snowboarder's footwear and a binding attached to the snowboard; retractably retaining a stake in association with the user; selectively engaging the stake with the line when snowboard stabilization is desired; and retracting the stake toward the user's body when not in use for snowboard stabilization.
14. The method of claim 13 further comprising the step of attaching the binding and the footwear while the stake and the line are engaged.
15. The method of claim 13 wherein the steps of retractably retaining a stake, selectively engaging the stake and retracting the stake include the steps of connecting the stake to a cord, and extending and automatically retracting the cord.
16. The method of claim 15 wherein the step of extending and automatically retracting the cord includes extending and retracting the cord from a housing at the footwear.
17. The method of claim 13 wherein the step of selectively engaging the stake with the line includes the step of forming a loop in the line and positioning the stake in the loop.
18. The method of claim 13 wherein the step of engaging the stake with the line includes user manipulation of the stake to implant it in snow adjacent to the snowboard and engaging the line.
