Anybody who is familiar with either going I90 vs I 84 in the end of January. GPS says it's about 100 miles shorter going I90 I just have not been down the stretch from butte down to Island park at that time of the year. Thanks in advance
I make that drive six times a year. I grew up in Ashton ID, 30 miles south of IP, we take I90 unless the weather is notably better through Oregon, it usually isn't though. 650 miles door to door and it usually takes us 9.5 hours stopping once for fuel in missoula mt.
