All are restricted to a 150 mile radius from USAFA that weekend(unless you get special paperwork which most likely won't be approved as a 4dig) . This past year we went up to Breck (within distance) which was nice as a 2dig that didn't need the sleep. As a 4dig I would highly recommend staying in or around C-Springs. And yes service dress is required for the doolies as it would be for any normal weekend off base. Unrecognized 4digs can be in civilian clothes once they reach the final leave location (home). Parents weekend isn't a leave period.
