+# TOWN CON INFORMATION
+
+TOWN CON is a celebration of tilde.town's 10 year anniversary featuring 24 hours of talks, art, and music by townies.
+
+TOWN CON begins at 0:00 UTC on October 11, 2024 and ends 23:59 UTC on October 12, 2024.
+
+There is an additional day of TOWN CON on October 12th for townies attending TOWN CON MEAT EDITION in Chicago, Illinois, USA.
+
+## DIGITAL EVENT
+
+TOWN CON's primary locus of reality will be here on the server in a text-mode environment. This environment will be supplemented with audio/video feeds as needed.
+
+Works submitted by townies will all be slotted into a viewing schedule to run throughout the 24 hours of the event. The text-mode environment will either show the submitted work or have a pointer off to where it can be consumed in a browser.
+
+The text mode environment will either be a HERMETICUM instance (if I finish the project in time) or just IRC.
+
+### JAMS
+
+Throughout the event townies are encouraged to cluster and collaborate on various creative **JAMS**. Re-run this tool and select _Propose a creative jam_ if you want to suggest one. Suggested jams:
+
+- 88x31 badge jam
+- forum software jam
+- game jam
+- dos jam
+
+## PHYSICAL EVENT
+
+TOWN CON MEAT EDITION takes place October 11th and 12th in Chicago, Illinois, USA.
+
+On the 11th we'll be plugged into the digital event together and on the 12th we'll do something in meatspace.
+
+### live music jam
+
+Meat edition guests are encouraged to bring small sound or music emitting devices. We'll set them up with recording system and do some jamming. Some synthesizers and a sampler will be provided.
+
+### VENUE and LODGING
+
+The venue is a converted warehouse loft located at:
+
+```
+Loft 606
+2605 W Armitage Ave, 
+Chicago, IL 60647
+```
+
+The venue has enough sleeping space to lodge everyone who expressed interest in coming in person, however some people will need to volunteer to sleep on couches. I have the venue reserved for:
+
+- the evening of October 10th (feel free to arrive this day!)
+- all day October 11th
+- all day October 12th
+- the morning of October 13th (feel free to leave this day!)
+
+The total cost to book this venue was **$8,637**. I've paid for it out of pocket and would love if townies could help chip in for the cost. As of right now (`2024-08-31`) I have received **$0** of chip in and will update this as I get donations.
+
+To learn more about the venue you can visit their website: https://www.loft606.com/
+
+### FOOD
+
+I'll arrange food throughout the event.
+
+- 10th 
+  - **dinner**: local restaurant food for dinner
+- 11th
+  - breakfast: bulk order from Colectivo
+  - lunch: sandwich fixins
+  - dinner: vegan deep dish pizza from Kitchen 17
+- 12th
+  - breakfast: bulk order from Colectivo
+  - lunch: sandwich fixins
+  - dinner: vegan mexican food from Quesadilla Del Reina Del Sur
+- 13th
+  - breakfast: bulk order from Colectivo
+
+There are also plenty of restaurants around the venue if people want to get their own food.
+
+### TRANSPORTATION
+
+The venue is accessible from rail, bus, and cab/uber/lyft. I have a car and can make myself available to pick people up and get them to the venue once they have made it to Chicago if they need. Depending on timing I might not be able to help, however. Contact via my cell phone (`~vilmibm/phone.txt`) to ask about my availability for a ride during the event.
+
+If you are driving parking might be tough in the area--I can offer a few spots by my place in Forest Park if you want to put a car there and then get a ride over to the venue.
+
+### ACTIVITIES
+
+I'd like to do a field trip on the 12th...Some potential ideas:
+
+- go to the nearby thrift store
+- go out to minigolf
+- go to a museum
+- go into the woods
+- just hang out and play synths (field trip of the mind)
+
+!!! TBD !!!
+
+## COMMS
+
+For any kind of emergency during the event please contact me via my cell phone. My number can be found at `~vilmibm/phone.txt`.
