A couple of items from my "wish list" of inventions I often think about:
1) A fishing rod that is freeze proof (AC/DC current running through the guides preventing icing).
2) A way of recording the radio while driving so you can play it back (or burn to CD) in the confines of your automobile...kinda like TiVo but for your car radio. A little hard drive memory added to the radio allowing you to pause a talk show/music and then resuming when ready.
The winter-net is here so bring it on.
