|We started the day at the nearest Walk In Clinic in Billings MT. I may have been affected by the altitude but I also had bronchitis. I was in and out of the Clinic in less then 45 min. and the thing I noticed most was the fact I was treated first and then they took down the information for payment. After waiting at the pharmacy we headed for Custer Museum. Its hard to imagine that such a battle took place here. We could have explored more but I was not up to doing a lot of walking. We spent the night in Spearfish, SD.
