cable length?

["{ brad brace }" bbrace2001]

>] ok, Gene has sent me a "frog logger" microphone (thanks!)

now I'd like to run about 500' of 3.5mm stereo cable down to
the creek (and maybe _in the creek -- the mic in a plastic
soda bottle) behind my place where all the marvelous
serenades occur this time of year...

I'm thinking of recording direct to DVD/computer if
possible... or HiMD

is the cable length a problem?
recommended vendors appreciated
