This must have been one of the most special photography excurions I had been on, ever.  It started with us driving to Stanly Park to park our car, since we knew Sunset Beach would be a no-go for finding parking since everyone would be at the Celebration of Light show where South Africa showed their best work.

I have been struggling on and off with EasyFrom DBConvert converting a Paradox 4 database to MySQL.  I would get this error intermittently:

[800A0CB3] Object or provider is not capable of performing requested operation.

Canada - Warmest and Coldest I have ever experienced

Submitted by pwnell on Wed, 07/29/2009 - 17:46

This is official.  The past 365 days I have spent in Canada mark both the coldest weather I have ever experienced at -35C (this was a few days after the screenshot I took below) with windchill at -42C:

 to the past week's temperatures of 38C (humidity index of 43C):

The coldest was in Winnipeg.  The warmest in Surrey (Pitt Meadows is the closest weather station to us).

 

Awesome.
