We have a very small and light 2-man tent. I bought it just before my first bike trip in 1994. It works for Trish and I. But once we started family camping, we bought a HUGE tent; it has a hinged door, light fixture with remote-control, and I can easily stand in it. We set up two queen-sized mattresses and a playpen inside, and still have ample room for storage. It weighs about 50 lbs, and takes about a half-hour to put up (if I have help).
I wanted something in between, that we could set up in the backyard in short order, and I could "camp out" with Heather and Addie and sleep in it over night. So, I looked on Kijiji and CraigsList, and found someone in Kitchener (near Victoria Park) who was asking a mere $30 for this tent.
The guy that sold it to me was honest and told me that the zipper often sticks and splits (the two sides don't interlock even after the zipper passes over). I bought it anyway, and he was right. The zippers were almost useless... at first. Then I did a google search and found out that zippers sometimes need to be lubricated. Dishsoap did the job.
Looking forward to some backyard camping.
