comma after introductory prepositional phrase
This is potentially controversial. I have removed all commas appearing in instances of '(independent clause), and (dependent clause).' For rules on when to use a comma, consider the sentence 'Bobby eats apples and eats oranges.' There is no need for a comma in this pattern. The same is true for more complex examples. The opposite is true when two independent clauses are combined. That is: 'Bobby eats apples, but Sarah eats oranges' gets a comma. Here's a link to some rules. http://www.getitwriteonline.com/archive/020204whencommabfand.htm
