Arremgee. Sorry for the tough trip. I think you should try out some of the multiple apps available for smartphones that allow you to see charging locations and details about the stations. Chargepoint, plugshare, the website: openchargemap.org, and many others give great details about what is available at these "EV sites." That would've saved you from driving over to a site with 110's several times and possibly would have let you know about NEMA 10-30's and amps available at sites you can actually use (chevy/nissan, etc.).
I would also recommend dressing extremely warmly and getting some toasty gloves if you plan on driving distances in the cold. Double socks, base layers, and a warm hat are nice too. My first drive from my delivery was 171 miles in some fairly cold weather. I had layers and gloves, used the seat heaters only, and while I felt silly going 65 in a 70, I made my planned 171 miles through some hill covered terrain with a ton of miles left.
eelton -- I encourage you to push it at least a little further than that. I work 45 miles from home. On a regular basis, I go to and from work, visit friends and run errands all in the same day without even thinking about my range or charging outside of my garage. Of course, this will be easier when there are more chargers. The Chicagoland area is moving quickly. There's even a Walgreens in Palatine that has a CHAdeMO.
