Southington opens at 3 p.m. March 12, and run until 9 p.m. Hours are 10 a.m. to 9 p.m. March 14, 9 a.m. to 10 p.m. March 15, and 9 a.m. to 6 p.m. March 16. Call ahead before setting out, as always this time of year. That's because Green Snow of St. Patrick's Day gives skiers a bittersweet foretaste of the green lawns of April – but skiing will outlast the leprechauns and continue through the silly season of swim suits and pond skimming.
