Last month I went solo from Tel Aviv to Heathrow to Oxford. In Oxford, I did all sorts of things like ride the bus, clambor up 3 flights to my husdand's apt. But I found the cobble stone streets not very conducive to me. From Heathrow I flew to JFK. Once in NYC, I met with an American P/T who I see from time to time. He told me that the "vest" we have all discussed is coming out in a new version, lighter and white. He says I need heavier weights. My understanding is that this also available in Denmark.
