My question is, why do you want to go to Antarctica (or the orbit, if you have the money for that), as opposed to a nice landscape near your home at a much lower cost?
Quite honestly, photo excursions are the best way to get revitalized and to help get that inspiration flowing through your veins. I have about 5 acres in my backyard and have the Niagara Falls just 25 miles. I am basically 30 minutes away from complete rural landscapes, the city of Buffalo, beaches (that get used for maybe 3 months here in Buffalo) and am right in suburbs so there is plenty to shoot but it does get "old" IMHO.
Absolutely nothing beats going out to a new location where everything is fresh to your eyes and where everything inspires you again... It could be the same stinking tree that is in your backyard but man oh man does it look so much better. Catch my drift?
At the very least, start your travels around your local state and national parks...
By the way Michael, your gallery is only maybe two hours from my home and I will have to take a trip down there one of these days in the Summer to admire your work...
