What do you bring to your projects?
Depends on the event but I always bring a change of clothes. The weather in Florida is very unpredictable, I'm not about to walk around in wet clothes because I got caught in the afternoon thunderstorm. I also try to bring my laptop, coffee, lots of snacks and bottled water, my Starbucks Community Service t-shirt and spares for new volunteers!!
I have to say, my DM is much better than I am at bringing supplies - sunscreen, granola bars, bottled water - she always comes prepared! I make sure I have some Advil in my bag as well :-)
I usually bring the camera (or camera phone). But, I've also been known to bring the wrong pair of shoes.
