MaryA pretty much said everything for me...
The only thing I want to add is that I am a little disappointed by some of the responses in this thread. That is totally fine if tattoos are not your personal preference, but I really hope some of you don't actually judge people as harshly as it sounds like you do from the tone of your posts. If you do, you are probably missing out on knowing some really great people. I don't think the majority of people with a tattoo are "trailer trash" nor do I think the majority of people without tattoos think that of those with them.
And I will tell you that I have a tattoo on my shoulder, not because it is relevant to my post, but because it is relevant to this thread ;]
