Will they let me bring a backpack on the rides at six flags st.louis?
All I can recommend is my own choice, cause I’ve tested this backpack for last 2 years. It’s called Swiss Gear Travel Gear 1900 and it was everywhere I was travelling. Here is a blog (url: https://10luggage.com/best-business-backpacks/) where you can find it and compare with other models and backpacks. But Swiss Gear Travel Gear 1900 is t he best choice in price / quality ratio.
