I tend to agree. I would second more of the advice here about demonstrating both good planning, and showing what touring is by working smaller trips first. I also think if possible involving your parents in the adventure is a good thing.

No problem with occasional check-ins to home. However, the problem you get with setting expectations that you'll phone in twice a day and continuously be trackable on the internet... is that sometimes technology fails or is flaky. For example, imagine if the spot on folks have a server down for an afternoon. You are still sending an occasional update but you don't get feedback that it didn't go out. While you are perfectly happy and safe, folks back home expecting more continuous tracking start imagining the worst. Compound that by accidentally leaving your cell phone somewhere and not meeting the twice a day checkin phone call...

I think it was valygrl that observed this was more a discussion of parent/child relation changes than touring. So it will be a bit different for everyone. In my own particular situation, that transition was helped by my going 1600 miles away from home to college and being the 3rd of 4 boys. Today, I think my mother would still worry about my travels on the road and might even breathe a sigh of relief if I wasn't touring through some of the places I've been. However, pretty long ago, my parents came to terms with us being adults and now have also gotten vicariously involved in my tours as well.
