Looking forward to Europe travel when I am certain the Covid coast is clear.  Have taken several ocean voyages.  Except for Switzerland and Ireland where we traveled by rail,my other European contact has been by ship.  Other countries visited have been Netherlands, Norway, France, Spain, Italy, Corsica, Egypt, Greece.

I thought I was continuing to fill out the application.  My response to Maria T Salamance and seewulf is thanks for the information.
