Would you let your son travel abroad?

Turned 18 a month ago, and I have a girlfriend who lives roughly 100KM (62 Miles) away from me, since we live so far away I'd obviously wanna travel to see her from time to time.

However, my parents refuse. Saying it's dangerous, despite the fact I'll travel by train and that I am old enough to well legally do what I want. I could just go without permission but that'd cause drama. Would you let your 18 year old travel that distance with no problem...?
