If your home state is your tax home then the trip to the other state would be deductible as a business-related travel expense.
"...Generally, your tax home is the entire city or general area where your main place of business or work is located, regardless of where you maintain your family home. In determining your main place of business, take into account the length of time you normally need to spend at each location for business purposes, the degree of business activity in each area, and the relative significance of the financial return from each area. However, the most important consideration is the length of time you spend at each location." Ref: IRS
