You can still get a tan w/ sunscreen. You should wear sunscreen period, even on a daily basis its good for you!! If you have a good base tan before spending alot of time in the sun you won't get noticeable lines, if any. thats why i use a tanning bed, like in my previous post cause I wear all kinds of strappy shirts during the summer once I get a base tan I have no problems w/ lines and I live in MT the only thing to do is be outside! Hiking, floating the river, at our lakehouse, etc!
