We told you about the delayed opening of Ice Castles Lake George until Feb. 3 — but the public will have an opportunity this next weekend to experience one aspect of the frozen attraction now under construction. Sun Community News reports the “Mystic Light Walk” and “Polar Pub” — both new this year — will be open for a special public preview Friday, Jan. 27, from 6 p.m. to 10 p.m. and Saturday, Jan. 28, from 4 p.m. at no charge.
