I coulda taken 287 from Helena to Three Forks along the Missouri and avoided that climb but the uber bike nerd website says places along that road suck for bicycles, heavy traffic no shoulder. Gonna be another late start 'cause I'm tired but 40 miles to Lewis and Clark Caverns State Park oughtta be doable. After that you rejoin 287 for a steep climb to Norris.
