By the time April rolls around the only places with decent amounts of good snow will be in Central/Northern NH, VT & Maine ... Killington has one of the the biggest snow-making systems in the world in cetral Vt, Attitash - Bear Peak in northern NH is pretty good & maybe the best is Sunday River in northwestern Maine & during a good snow-year you'll find plenty of skiing for a week, however this year has been pretty crappy, so be sure to research conditions carefully before spending a lot of money.
