I like your style!Yep there is that too.
The times it was really useful was in setting up a tent with sleeping bags and cooking gear etc then cycling back home leaving the trailer there in the tent in order that my partner and I plus the dog could travel up to it by Train/Bus without having to cart all that weight (neither of us drive) then after a week or so return home on public transport and I'd cycle back up there and pack the trailer up and cycle home again. You may think this a bit 'long winded' but I got to cycle around 100Km to the campsites (in the Peak district) which took most of a day with the trailer set up the tent and have a kip then have a bimble around on the bike before heading home the 3rd day. It's only about 4 hrs to get home 'sans trailer' so an early start for me meant we could all leave Leicester before lunch to arrive at a ready pitched tent in the evening. coming back was the same thing in reverse.
