As a wisconsin folk, I can head out from here earliest would be like 7:30 from Fox Lake thursday morning it will take me about 3 to 3.5 hours to reach the oasis. Would 11:00 to 12:00 not be early enough for everyone else....? I know we were supposed to meet at 12:00 last year at the same spot...
The oasis is on I-294. Here is the info for the Mobile gas station located next to the oasis:
