Read a gear list before you shop, not in the aisle. These cover sport, builds, travel prep and big purchases. On the Hockey Gear List, stick length should reach about the chin with skates on. The Football Gear Checklist puts a mouthguard on every list, and the NFL's flag page suggests a backup pair in the bag. The PC Build Checklist warns against skimping on the power supply. Big crowds can mean spotty service, so the Protest Packing Checklist starts with a fully charged phone and a spare battery. Recruits and their families can open the Basic Training Packing List, which starts with paperwork. Boat owners get the Boat Maintenance Checklist, where the forgotten drain plug is the classic mistake.
