111908samrudolph.jpgThose blissed-out Christmas tree sellers from Quebec who camp out on every other corner this time of year are worried that the economic tailspin is going to seriously harsh the holiday vibe. Scott MacKinnon of Elite Balsam Products tells the Daily News that everyone's "a little bit nervous." In order to appeal to budget-conscious tree buyers, vendors have cut prices by 25% by buying cheaper trees. But other sellers are exhibiting unshakable faith in New Yorkers' need to fill every cranny of their apartments with balsam fir needles. One big seller in the city, Dr. Jane Waterman, insists that after three decades in business, her best season was right after 9/11: "In bad years, we find people buy trees and cut back on what they spend on gifts." Plus, "We're thinking everyone is so excited about the end of the Bush regime and the election of the first black President that they'll buy trees."
