Tent Services is a very affordable service currently based in my garage in South Minneapolis that provides Expeditionary Conversation Tents for checkout. The tents are meant for 2-15 people to undertake an expedition in which the primary purpose is to converse with friends, strangers, family and significant others or to hold a meeting, class &c.

There are 6 tents: two each of small, medium and large sizes. They are made of canvas and are easily set up, even if you have never set up a tent before. They are meant for expeditions to indoor spaces where together you will create a space for conversation.
