Hi folks. Is this course specific to your regain, climactic conditions and zone in the USA?
I'm in a region within South Africa (Kwazulu Natal) which has a hot, very humid sub-tropical climate, with no winter freeze (our winter would probably be considered a cool summer elsewhere, low 20 C) and summers ranging in the high 20C to mid and high 30C (80-high 90F). If most the concepts are specific to your area, I'd rather not buy it, as it's a lot of money, with our current exchange rate of over R18 to 1 US dollar.
Thanks
Gavin
