The meets attract members at all levels from raw beginners to experts in their fields and I have never met anyone that was not more than willing to share their skills.
People often imagine that you already have to have certain
skills or equipment to go to a meet but you might be surprised to find very little is really needed.
They are usually held in established campsites so basic toilets and water supplies are not normally a problem. You will of course need some form of shelter but a normal tent is quite sufficient.
Many turn up with tarps and hammocks which is fine too but most sites do not have the available materials for building natural shelters.
Bring something to eat and if necessary the means to heat it. Some sites allow ground fires, most require fires to be off the ground for safety reasons. Again, there is nothing wrong with bringing a simple camping stove if you like.
