Food truck operators at Lake George Winter Carnival were warned recently to stock up so they are ready to meet the demand expected at this weekend’s Lake George Winter Carnival. Outhouse races, which begin at 2 p.m. Saturday , will host more participants than they did on Feb. 3, since more people have heard about the $2,000 in cash prizes for not only the first-place winner, but those who race the fastest in preliminary heats.
