Toilet Paper - To flush or not??

I'm a little embarassed to be asking this question  :-[ but our friends (who do not have a TM) told us that we should put a little garbage can in the bathroom for 'used' toilet paper.  They said flushing the paper gums up the sewer line, the filter, etc., and makes it a bear to clean.  And that we should empty the garbage can every day to remove 'odor' and unsightly paper.

This sounded a little odd to us, and I smiled at my hubby and said I'd ask all of you first . . . we're heading out for our very first camping trip next weekend 4/18.

Is it okay to flush the paper?   :P

Thanks for your help, again!!!
