I'm not sure how often Elon or others look at the forums but I thought it would be interesting to post a thread with suggestions for supercharger locations. My guess is this has been researched at length already and is only a matter of time before we see the expansion of supercharger locations, but I thought it would be interesting nonetheless. For the record I am not a Tesla owner yet but plan to be in the very near future, it's not a matter of "if" but "when". While I will have another vehicle I could use for road trips if need be, I have a feeling as soon as I get the MS I won't want to leave it in the garage for a road trip (or any other time I leave the house).
Locations I would like to see:
I-45---Huntsville, TX or Madisonville, TX: Either location would be ideal for the drive from Dallas/FW to Houston or Galveston. Madisonville is a very small town but is close to the halfway point of the drive, and there is not much north of there all the way to Dallas. Madisonville makes more sense to me because it's almost exactly 1/2 way in either direction (from Galveston), and should be doable with either battery going in either direction.
I-35---Temple, TX or Waco, TX: Either would be a good stopping point between Dallas and Austin. You could probably drive the whole way on one battery charge, although with the 60 kwH battery you would be cutting it pretty darn close.
I-35---San Marcos, TX or New Braunfels, TX: Between Austin and San Antonio
Having one in the major cities is an obvious bonus, but being able to make road trips to locations that might not be doable on one charge would be awesome. I'm not sure how many Tesla owners are in TX just yet but we already have a service station here in Dallas and two galleries in the state....
