I don't think there is one yet, but I'm sure it could be started up fairly quick! I bet you that if you follow the Grand Glitch Housing Circuit, you'll encounter plenty of fireflies, though.
Hi Molly--there isn't an official route as yet, but one is in the works. Stay tuned to the Housing Resource Routes group--that'll be your best bet for updates on this.
Hi Molly, just hit on one your friends - add them to your signpost and see where they take you. I normally follow the bottom players on each sign. I've been roaming a lot the past couple of days and have found fireflies to be on almost every home street I've come across! Good luck : )
Yes most people who have done anything with their streets have one of everything out there it seems. Normally there's a jellisac mound by the fireflies as well so you'll get both :)
