Traveling...

I'm leaving for New Orleans tomorrow to attend a conference for my job. I hope to squeeze in some sightseeing while there and of course eat some of the good food New Orleans has a reputation for providing. I don't intend to buy much except food while I'm there which I will get reimbursed for when I get back. I doubt I will have computer access so I probably won't be posting again until mid-week next week.

Does anyone have any suggestions for inexpensive sightseeing options I should try out while in New Orleans?
