7/18: We biked into Billings in the morning and found The Spoke Shop where we 
stocked up on patches, got a new tube for Tyler, trued Lydia's rear wheel, and 
tried to unlock the secret to mounting Katie's handlebar bag. We continued on to 
the grocery store for a tasty lunch with rotisserie chicken and loads of fruit, 
then embarked on the rolling hills to Hardin. The hills proved to be tough, and 
after a pb&j rest stop we decided to find a motel for the first time since 
Helena. Making mac and cheese with chicken and corn for dinner, we had a great 
nights sleep on the phenomenally comfy beds before moving on for our last day in 
Montana.
