AA True van only gets 12 mpg but it saves me 120 bucks on motel bill.It runs like new.It has refrig,and I like can tuna,Lox,and Ocean Spray Cranberry.It has 5 speaker sterio and lots of storage.I love my van + I have a few bucks coming in on M&M. When nyou collect SS and have extra $$$$ coming in gas is not a big expense.Plus I shoot great pool when shooting for a Bud or 5 bucks. TreBert

California is already full of Aliens and spaced out entities, and Wallmarts

California's hollywood  continually  broadcasts out fake history, and 
propaganda to support paid politicians.

now, God is *getting* California, and thanks to its democrats cailfornia 
will never solve its water, or its tax problems.

California needs to be walled off, and its beaches and surf relocated to 
Texas.

Once upon a time when Mars had great oceans just like Earth,and it was closer to the sun the Martians eat lobsters clams and cod.They washed it down with beer.I'm telling you all this for I'm looking to work with NASA. TreBert

... and now, they are not.

We had to go to Mars to find an example of something that changed?

Mars never could have had an atmosphere like Earth.It never rained on Mars not even once apon a time.It has the tallest volcano good reason why.43 years ago a lander came down on a huge dust storm,and I was hit by a dust storm driving out of Vegas. Today I was in a swimming pool that has more water in it than all that NASA will ever find on Mars  TreBert
