The only place that I'm aware of that is left would be Tucks and maybe Katahdin which is practically in Canada. If you're really desperate for some turns I would make the hike up to Mt. Washington, you can probably drive to the top because I saw a few people just under the summit skiing a decent sized patch about a week ago. Also if you have a pickup truck, a trailer, or a tarp and a lot of trunk space you can always go to a hockey rink and use the ice shavings as snow (it works unbelievably well). Just bring some shovels and fill your car then take it home and dump it on a hill.
