Our team does several things during offseason. I hope these can give you some ideas:

1. Programmers meet to learn programming. I learned programming during Saturdays last summer. I know if I tried to learn programming during build season I would've been completely lost!

2. Community service. We usually participate in adopt-a-road at least once during the summer (as in we clean up a stretch of road). We also do some other events offseason, like cleaning up our school's football stadium after games, which is much later in offseason (we get paid too!)

3. FIRST summer camp. This year we're planning on doing a 'summer camp' for robotics kids. We have several FLL and JFLL teams and a FTC team and we're hoping to do something with them this summer.

4. Offseason cleaning. We're also planning on a mass clean-up of our new 'robotics center' (one of our elementary schools closed down and we are generously allowed to use the gym! This means we have much more room to put scrap metal and other junk so we have a bigger mess).

4. Team picnic. Our team hasn't done one since I've joined (or I don't remember), but it would be a great thing to do to keep the team connected.

5. Offseason competitions. Michigan has MARC, but I don't know what New Jersey has. I'm sure there's an event somewhere your team can attend. They're always a blast and you can make new friends with other teams.

6. Recruiting rookies. As soon as competition season is over we start making posters for students interested in joining robotics.

7. Training rookies. This happens much later (as in early preseason), but it's good to get a head start.

8. Getting sponsors. We try to get some sponsors during offseason.
