I could send you so much traffic that you'd be calling within 15 minutes askimg me to turn it off

There's a lot of threads around here on this subject - off the top of my head, the popular ways of going about this are:
1 - do a search for some general keywords on your niche in a search engine & look for link lists that already have their category pages listed.
2 - trial & error - try out a few sites that have a category for your nice & see how it goes.
I'm sure others will chime in with some tips
