Disposal of an inflatable boat

Is there a place to properly dispose of an inflatable boat?  I bought an Intex Mariner 4 about 2 years ago and it's leaking air.  I have to registered it with the DMV because I put a trolling motor on it.  How to I properly dispose and un-register this thing?

I'm sure someone on CL would want it and repair the leak. 

Once you junk it, you simply surrender the Certificate of Ownership to the DMV within 15 days.
