moving: 2 day drive..how's this sound?

I moved from Dallas to Phoenix with a guppy, two platys, American Flag fish
male and a Rubber Lipped Pleco in a seven gallon bowfront. All I did was
drain the tank down to 1/3 full and loaded them into the back of my Explorer
with the rest of my crap and three cats. No fancy car cigarette adapter or
anything of the sort. Loaded a 5 gallon bucket with water from Dallas
(already knew there would be a BIG difference in water conditions between
Dallas and Phoenix as I had checked out Phx water on the website) and when I
arrived in Phx I refilled the tank with Dallas water and then began the task
of mixing the water slowly over the next few weeks until they had adjusted
to Phx water. Didn't lose a single fish and still have them all almost a
year later! I would think the danios and swordtails would make it as these
are pretty tough guys but I don't know about the rest... I plan on using the
same technique when I move to the Pacific NW in a year or so only this time
I will have a 55 gal. to deal with. I only plan on taking the original fish
I brought here with me as they are my favs but now the male American Flag
has a girlfriend to consider and there are a couple of Dojo loaches and a
tank full of plants I don't want to get rid of so they will probably come
too. I still plan on doing the same thing as it has worked once... only on a
bigger scale this time.
