dinosaursmuseumLike to visit the Houston Museum of Natural Science for free? Bank of America cardholders can take advantage of “Museums on Us“–a national program that provides free museum admission the first weekend of the month to more than 70 participating museums through April 2009.  In Houston, that free museum equals the Houston Museum of Natural Science on March 7-8 and April 4-5.  (Free admission is limited only to the cardholder, according to the official B of A site.)
