Any suggestions for where to hold a winter Boot Camp?

I have a year round bootcamp in Northern California and so far we have been outdoors for 14 months, rain or shine! Sometimes it’s a challenge but we manage by finding shelter such as an overhang on a building or we use parks with cabanas.

However,if I had to go in I would look into a Senior Center, Youth Center, Dance Center to rent.

I must add the I find working out in the cold air is exhilirating!
