Master R.,
As you can see, I work hard to find solutions to yours comms problems
Here, below, is a solution strictly for your own side of the big waters for those windy or cloudy days, unless of course you have collected enough AIRMILES for transporting PONY and RIDER with mail, xpressly, to our distant shores, in which case after the flight it would be "RIDE-ON/CARRY ON" for Master Pony Express and Pony.

I DO hope this helps.
