Some years we camp a lot, others not so much.
I think it is worth it but have been camping since before it was the in thing, back in the days when people camped because they were poor!
We camp all year round if we fancy it (one of the tents has a stove). We bought that tent for a long trip to Scotland and justified the spend because we would have spent at least £1500 on a cottage for three weeks.
We justified the other very expensive tent because we used it for three months the year we bought it, etc., etc.
Pre wood burning tent we would only camp from May to October. We don't use EHU, some people extend their season with that.
Some years we are away a lot at weekends, others not. I am prepared to drive for up,to three hours after school on a Friday for the weekend.
So, yes, I would say it was worth the outlay. You don't have to push the boat out cost wise in the beginning. When I was at uni I had a little ridge tent, air bed, sleeping bag, stove and that was it!
