We headed once again into the mountains of Montana. We had to drop Peter and Steve off along the way at a motel in South Dakota. After much disussion it would appear that Steve has actually contracted "West Nile Fever" this would have come from the mozzie bite. It will just have to run its course. Although slightly better, he said he feels like he has been run over by a train. After a 400 mile trip James and I ended up back with them later. Going west from Spearfish SD through Wyoming and into Montana you reach the end of the Great Plains, suddenly. you feel like you are going to drive off the edge of this continent. Then though the clouds you can see the expanse of the snow covered Rockies, whilst your thermometer reads 83f. The storms were developing over the mountains and starting to move east north east. We stopped to decide our plan of attack on the site of the Battle of Big Horn. It is a Cheyenne Indian Reservation. It is sad that each home is marked by 20 or more scrap cars. I guess their only way of making money is by selling the car parts. We chased the storms most likely to produce a tornado. They were very active and we actually "Punched the Core" which put us in front of the storms. The lightning bolts rained down all around hitting everything in sight. We kept moving a little in front of the storm and stopping to shoot lightning shots. At one point all the aerials on our van started buzzing we knew then we had to move. The storm was kind to us the road we used to keep with it took us home to Spearfish and our motel.
