[FoxHunt] MicroHunt vs Pocket Fox.

[R. Simmons]

Thanks for alternative opinion...

VERY nice website BTW... I like the complete posting of the rules, I don't
think I've seen that with any other American website.

 I don't compete in ARDF but it looks appealing... DF'ing multiple TX in a
relatively small area ( and on foot ) means strategy and tactics must be
pretty important... it's not just technology, and it's not just athletics.
