After they paid the entrance fee and Sam finished using the restroom they went to the rock climbing area, after getting strapped up Jake had to open up his big mouth.
"So Alison since you claim to have experience and are supposedly ready for the pressure let's make things interesting. If you manage to reach the top of the climbing wall first I'll treat us all to lunch but if anyone of us manages to reach the top first you're paying for lunch. What do you say?" Jake stuck out his hand to seal the deal.
Dean saw the spark in her eyes before she even spoke, "This will be interesting," he muttered.
"Well how about we make it even more interesting," Alison smirked, "If I don't come in first for 2 of the 3 activities I'll buy everyone lunch for a week, but if I do you're going to treat the group." Alison paused with a big smile on her face, "Do we have a deal?"
