I'm 50 and I'm going to a 'rock concert'. Should I take GPS?

Leave the drugs alone mate!! :0)

No need, just dress your family in dayglo yellow and pink (very trendy these days), and with the blue neon lights you'll spot them from a mile off. Plus your family would be quite a talking point among your fellow members of the audience. (That's the second time today that I've recommended the use of dayglo in an answer, could this be a fetish? Oh, I do hope so, I've never had anything quite that exotic before!)

Having a method to easily locate one another in a busy venue is a great idea. But taking expensive electronics to a gig is inadvisable because it exposes you to additional security checks and makes you more of a target for pickpockets and thieves.

I am in your age group, and when I go to concerts with my teenage son and his friends, I get everyone to set their mobiles to vibrate+ring, and conceal them in a pocket. Then we can text each other if we get separated.

We also agree a central meeting point when first arriving at a venue; somewhere we will all congregate if we get separated, or at a specific time (eg to catch the train home).

Take some earplugs. I'm 48 but not as old-sounding as you......."the young people"? You're not exactly old, are you?

It got very loud at the Rolling Stones concert I went to last year, and left a ringing sound in my ears for a day afterwards!

I would take some viagra with me!

You should definitely all have cell phones.
