What should I get my boyfriend for his 18th birthday?

My boyfriend's 18th birthday is a month away, and I feel like I haven't gotten him enough (I love to buy people lots of things). I am planning on having a picnic atop the Blue Ridge Parkway to watch the sun set with him in the evening. And then, once the stars come out, I'm going to give him his main gift (I got him a star!). Also im going to get little things like cologne and clothes. Any other suggestions I would gladly accept! Thanks!
