I loved Mary Poppins! What a woman!!!

Anyway - I never leave without the usual - helmet, sunglasses, cell phone, money, spare tube, tire levers, patch kit, food, beverage, ID, sweatband, gum ( must have gum) and I also have the "teensy weensy fold up tool"

When I first got my bike I started thinking about riding alone without knowing how to change my tire - so I pulled the front wheel off one afternoon and spent the rest of the day learning how to change the tire - and wouldn't you know it - I punctured the tube doing that and then REALLY had to change the tire
