The important details are obvious: It's Tuesday from 4 to 8 p.m. One cone per person. Since we're talking after school, expect lines and charge your phone beforehand (the company wants you to hashtag the event with #HDFreeConeDay). For additional details, keep reading.
In other news: Not all locations are participating. However, you CAN do a specific search for spots offering the deal at this link. From what we could tell, the following outlets are all in on the fun: Irvine Spectrum, the Shops at Mission Viejo, Outlets at Orange, South Coast Plaza, Downtown Disney and Fashion Island.
You can even use the same search engine to search by flavor. H-D appears to be pushing the strawberry and green tea flavors for springtime. Limited-edition tastes include banana split, bourbon pecan praline, midnight cookies & cream, and peanut butter pie. I'm still missing the best flavor ever: sticky toffee pudding.
