Anniversary gift

Ok so my my 2 and a half year anniversary is coming up next month. I wanna do something creative for my hubby so I decided I'm gonna do a scavenger hunt! Like I wanna send him around town to get clues. I know one will be sending him to get a hair cut and at the end the stylist will hand him his next clue. I will have everything prearranged and prepaid. And eventually it will lead him to a restaurant where I will surprise him with dinner. I need ideas
