Where the retreat is being held, is ran by people who lease from the State of Michigan.  You must agree to comply with the rules to attend the retreat.  Here are their rules:

Hi all ,
 •'The  Rules'' are  for our camp. The  State  of Michigan has
laid out some  very  plain  rules  that  must  be enforced. I   could  lose  m y lease  if n ot, so these  rules are not negotiable:
1.   Abide  by all the  laws of the State  of Michigan.
2.   No Smoking in any  building at any  time!  (I believe the current law  in the State  of Michigan enforces a ban on smoking on any State property, and  yes. even  though I  hold  the  lease.  thi s i s State  Proper­ ty).
3.    No dogs  or other  anima l s are a ll owed  in an y of the  buildings at any  time.  I f you  bring  your  pet it will have to be under  your  direct  control  at all times  (on  a leash)  and chained or crated  outside at night.  It would  make  your  vacat i on, and  the vacation of those  around yo u more  pleasurable if yo u made  ar­ rangements to ha ve yo ur pet cared  for at home  whi le you are  here.
4.     Exceptions to rule 3: Personal service dogs/animals (seeing eye dog  etc.).  Dogs/animals used  in presentations for educational purposes.
