Hi Guys, my wife and I are due to attend a conference in Vancouver in early May 2012 visiting from Australia with a stop-over in San Francisco. Since we're travelling a long way, we thought we'd take a month's vacation in Canada and Northern USA. All the seasonal weather charts say May is a great time to visit but looking at indicative temperatures for May this year, average temps are 15 C and rainy. We had intended taking the Rocky Mountaineer across to Banff then flying to Toronto, Quebec and then to Boston and NYC. I know we don't have a crystal ball when it comes to long range weather forecasting but we're wondering if after the conference in Vancouver, we should fly down to San Fran Cisco then straight to NYC and do the trip in reverse with a view that by the time we get back to the Rockies and Vancouver, the weather might be warmer as we get closer to June. What do you folks think? Worth the reverse trip or should we just go with the original plan to head East across Canada from Vancouver?
