Every third Sunday of the month from April-October. Ace Sales has setup at this show since it first started. This is an excellent event and quite different from your normal flea market. You never know what you will find. Everything from computers, electronics, robots, solar to tools, 2-way radio, consumer goods etc.
Hint: The first and last shows are simply amazing. One reason is that many vendors load up over the winter and have fresh merchandise and the other is the fact that in October no one wants to take it all back and hold it for another year.
We normally setup outside near the garage at the end of the first row.
This event is at the corner of Albany & Main St. in Cambridge, MA
