My aunt and uncle w/ my cousin and his new wife just drove from Haines, Alaska to Anchorage, Alaska. If my aunt complained about potholes in a toyota corolla then they're probably big enough to swallow a 7. Apparently the canadian side of the alcan highway is in need of maintance while the US side is in good shape. Last time I drove to Anchorage a few years back the frost heaves were pretty bad on the canada side. Enough to lift you out of your seats when the driver doesn't see them and hits them at 80mph.
