Agreed, that's not the right choice then.

What would you do for the access= then? Nothing? And where does the
bicycle go? And why do you choose these types and not others whose
access is restricted?

It's not on the same date every year, so that would make that impossible.
I guess anyone who would want to access this road would know, or be
prepared to find out, when Memorial Day is.
I believe it's the last Monday in May, btw.

So this particular case could, as I understand it, not be covered by
the current temporal access restrictions scheme?

It looks horrible, and would require a JOSM plugin to be manageable
for the average mapper.

How about access:website=http://www.slcclassic.com/utilities/ud_citycreek_reservations.htm#anchor4
This would be unsuitable for routing but would at least give some info
for those who are really looking for it.

Ah yes, someone put that in there before me.
