I take my boxes out a fair bit, barbeques, down the park etc. Sometimes get some funny looks but its mostly all good.
I took a box out with me recently in the boot of my car to work, I try to always have one in there just in case. So i was in a nice seaside town for the day with work, as it struck luchtime i grabbed a sandwhich and sat on the beach in my suit with a boomer and a sarnie. Two chicks came over and sat with me, I was playing some Tribe Called Quest, and they sat and chatted for ages, before long i had a group of around 10 chatting, looking and getting there photos taken with it.
Love it!
