Just back from HU Russia 2018.
Here is what I got for my registration:
Free camping in a nice spot.
Free soft drinks, water and

during presentation times.
Free tasty dinner every evening.
Free tea, sweets and cookies every evening.
Free banja every day.
Guided rides on and off-road every day.
Enduro Training.
Interesting presentations.
Chance to order low priced breakfast and lunch in local restaurant.
Well organized meeting and russian hospitality in a very nice location.
Can not see anything wrong on registration fee for western travelers.
But lot of money for most of Russians and people from eastern Europe.
Defenitly want to go there again.
Just my 2cents
