If you are an alien and you want to take over the city of Grand Rapids, then this is your weekend to stage that attack, as the streets and halls of hotels will be filled with comic fans many adorned as their favorite character who will descend upon our fair snow-covered city for the ever-growing Comic-Con. You'll blend right in with the costumed crowd.
If you know what Comic-Con is, then you are already preparing your outfits for the weekend festivities that sprawl from the DeltaPlex for the convention to the area bars and businesses ready to receive you just as you are. (Area merchants will only take cash or credit cards, so hold your geeluck-luck bills for your next outer space stop back in Zoltazick.)
If you do not know what Comic-Con is about, then start here and work out where you will land your ship this weekend. It will be worth it no matter where you land or how you arrive.
Details here for all programming, including when Nichelle Nichols a.k.a. Lt. Uhura from the original “Star Trek" will be at the event. LINK: Complete List of Comic-Con Events
Admission: $12 - 35 with special pricing for kids.
