Quick Suntanning Question

[Macdaddy Warsaw]

Hey, I was out tanning on Thursday and caught a decent bit of color (I was outside for probably 2 hours). I got a lot of sun in June, not so much in July and since I recently started dating somebody, I was trying to not be a pale, pasty poker player (ALLITERATION). That said, I was pretty pale before and got a bit of sun burn but nothing too bad, just enough to make me pink in some places instead of brown (specifically on my chest and the back of my legs). I was hoping to go out tomorrow (er...today) and pick up some more color since I'm seeing her again on Wednesday and it'll probably be raining on Tuesday (oh the things I do). Anyway, my chest is still a little bit pink and hurts if I scratch it but not really otherwise.

Question is: do I face any serious injury if I go out at around 1 till like 2:30 or 3 and try to catch some rays?
