Just take off in Atlanta and climb to 6500'. Stay at that altitude and
when you get to Boulder, you will be at pattern altitude! (actually
pattern altitude is 6300'). Run at full power. Lean for best rpm (at
6300'). See how far out the lean knob is? That is how far out it should
be for takeoff too (plus 3 half turns in). We lean on the ground at
runup for takeoffs at these altitudes. Learn how to do that if you
don't know how. This time of year is bumpy below the cumulus and if we
have rain, it is thunderstorms you can see and go around. So go around
them. The weather is good for flying in the summer in Colorado. Have
fun and see ya

Good point about leaning for takeoff power. This is not even mentioned
in many checklists, and is likely to be neglected by most flatlanders.
