Currently sitting 27 miles south of LHC, I have not seen the, Winter Activities/Events, publication for the area yet, and can't find last years for the Balloon Festival contact info and dates. I'll track your post, and post any info I can round up.
In the 6 years I've been in the area, there have been issues with high winds on the event days, JMHO, I wouldn't be shelling out in advance for any tickets.
