How It Works:

Grab Your Passport: Pick up your event passport at any participating business—you choose where to start!

Travel throughout our downtown and earn stamps on your passport:
1 Stamp: Visit a business and chat with someone from the team.
2 Stamps: Make a purchase or enjoy a service.
3rd Bonus Stamp: Find a small business within a shop and engage with them!

More Stamps = More Chances to Win: Each stamp = 1 raffle ticket for fabulous prize baskets filled with goodies from our businesses.

Collect stamps from 5–8 PM as you explore Hudson. At 8 PM, wherever you finish your journey, turn in your passport (with your name, email & phone listed clearly so we can contact you if you win) to enter the raffle.

Raffle Prizes: We will have a minimum of 3 amazing prize baskets (maybe more!!), packed with items from our She-E-O businesses. The more stamps you collect, the higher your chances to WIN!
