I have sites in three main categories:

Travel - strictly travel related material(maybe some real estate) and with a PR 1-5
General(any niche) - there i can post pretty much anything unique, they are also with a PR 1-5
Health - three sites, PR2, strictly health/dieting/weightloss/etc

I need links to one of my travel sites(they can come from any niche,except casino and adult) and in return i can give you links from any the sites in these three categories. If you are at all interested contact me and i'll explain further.
