Two more sites have opened, both on I-80 in Nebraska: North Platte and Grand Island. It's now possible to travel from Omaha to Ogallala or maybe Sidney, NE, or else Sterling, CO easily; one more's still needed on I-80 or 76 somewhere from Ogallala to Sterling to reach Ft. Morgan (184 miles uphill) with no worries - I like Big Springs, 5 miles east of the junction of I-76/80.
On the down side, there appears to be some problem with the QC site in Commerce, Georgia, as it's been added and removed from the 'open' list and map at least twice and is currently shown as coming soon, so there are 31 rather than 32 open sites total.
