The easiest thing to do is do a Google Maps search on the area. You will want to make a list. From my experience the most useful types of locations to investigate are the following, in order of preference:
- Parks (for the outdoor option)
- Schools (public and private… more on this later)
- Indoor soccer and indoor turf sports facilities
- Gymnastics or cheer facilities
- Your garage
- Martial arts schools or studios
- Community centers or senior centers
- Grange halls
- Boys’ and girls’ clubs (depending on location this may or may not be viable)
- Churches
- Industrial warehouse spaces
- Unused rooms in commercial and retail spaces
- Gyms (last for a reason)
