My initial post was based on transmissions I heard while flying through northern Montana on my way to Oshkosh.
Yesterday, on the way back, we landed at Lethbridge to clear Customs. The FIC operator was pleasant, friendly and strictly "by the book". After our initial call, he gave us the current weather and then asked our intentions. His responses to all our subsequent position calls were just "Roger".
A far cry from the "clearances" that I heard a week ago from the operator at another Southern Alberta FSS that shall remain nameless.
