Use 3 groups with one coordinator per group. 00:00–00:10: welcome and explain the activity. 00:10–00:20: distribute 33 trail cards to each group. 00:20–01:05: run the main activity. 01:05–01:20: collect feedback and reusable equipment. 01:20–01:30: clean the north gate and check the inventory.

Count the 99 trail cards before visitors arrive. Confirm a clear entrance and an accessible work area at the north gate, then give each of the 3 group leads the same timing sheet.

Supplies: 99 × $11.35 = $1123.65. Reserve: $1123.65 × 0.10 = $112.37. Planned total: $1236.02. This is a planning calculation using the supplied prices.

Remove 33 units, leaving 66. Supplies become $749.10; a 10% reserve adds $74.91, for a total of $824.01.

Join Weekend Walking Group this Saturday at the north gate. Meet neighbors, learn together, and take part at your own pace. We will share the available trail cards across small groups. Supplies are limited, so please check with the welcome desk when you arrive.

Weekend Walking Group Saturday · north gate Welcome! Ask the desk about available trail cards and today’s small-group activities.

```python import csv def read_inventory(path): rows = [] with open(path, newline="", encoding="utf-8") as handle: reader = csv.DictReader(handle) if reader.fieldnames != ["item", "quantity"]: raise ValueError("Expected item,quantity columns") for line, row in enumerate(reader, 2): name = row["item"].strip() quantity = row["quantity"].strip() if not name or not quantity.isascii() or not quantity.isdecimal(): raise ValueError(f"Invalid inventory row {line}") rows.append((name, int(quantity))) return rows # Example row: trail cards,99 ```

The row `trail cards,99` should pass. The row `trail cards,-1` should raise a ValueError because a negative quantity is outside the stated inventory contract. An empty item should also fail.

Handover — Weekend Walking Group Location: north gate; day: Saturday. Inventory: 99 trail cards, allocated as 3 groups × 33. Before opening: count supplies, set the welcome desk, and confirm group leads. During the event: record shortages and visitor questions. After closing: count returns and write one improvement for the next meeting.

Ask: “Were 33 trail cards per group enough for the activity, and which step created the longest wait?” Record the answer beside the returned inventory count.

You are welcome to check in at the desk when you arrive. A coordinator can explain the current activity and see whether a group has space and spare trail cards. If the activity is already full, we can help you observe or find the next joining point.

Avoid guaranteeing a place or a set of trail cards before checking the group capacity. Keep the reply specific to the north gate session and offer a clear next step: speak with the welcome desk.
