The one my boyfriend took me to is Howling Woods Farm in Jackson, NJ. You have to make an appointment and they don't list their address unless you do so they don't have people dropping in unannounced and upsetting the animals (which is smart). They ask for a $20 "donation" from all visitors, but...
I had to change my avatar to apply for citizenship, but it still works :) The white wolf is Bandit, who was also in "The Sorcerer's Apprentice."
Seriously, take your girl/boyfriend to a wolf sanctuary. Best. Date. EVER.
