What would you say is the roughest terrain the B-Ready can handle well? Dirt paths? Some rocks, dirt path? Bumpy grass? Gravel mixed with dirt? Mulch nuggets?

We went to the State Fair last night and it made me second guess myself as to the durability of the B-Ready. I really like it because of the parent facing option, and its our top choice, but now Im wondering if we need something with bigger, more rugged wheels?
