You have a $100 budget to get gear for going on a camping trip for at least 3 days and nights. You will be hiking at least a mile and a half through woodland. The temperature is a moderate 70 degrees farenheit and the weather is uncertain, with a chance of rain but likely sunny. What do you buy before setting out for this trip? Spend as much of the budget as possible.

What are your essentials?
What do you enjoy, but could leave behind if it's out of budget?
What are the best deals around when going on the cheap?

Clothing, food, and water are not included in the budget, and have already been acquired.

Pic somewhat related; not my gear, just something I found for the thread.
