Cost comparison MUST be calculated for all travel (except their commute to Cheyenne) for travellers that reside out-of-state, and the cost comparison must be computed as if the traveller were departing from and returning to Cheyenne under normal circumstances (no contructed/interrupted).
If POV mileage reimbursement is being requested for this trip, be sure to check that the # of miles entered by the PM in the POV section is from Cheyenne->destination->Cheyenne.
