You may have upped the rewards but, believe me, nothing you could offer would make me want to visit you more than I already do.
When my nephew comes here to visit, he usually goes home, back to the States, with a bottle or two of my mead. He's my sister's youngest so maybe, he'll effectively increase the pressure on my sister to drive me up to you.
I have not given up hope yet.
I still think fondly of the time spent together with Blueblood when he came to Israel and I had a chance to do some touring with him. For those who might wonder, I'm that second person in his avatar on the forum.
I'm always open to hearing from forum members who are planning to travel to Israel. There's a special "language" that keeps share.
