Wow, early March is pretty early. The earliest I've ever been able to get my studs off is March 28.

I carry a spare tube and glueless patches. The glueless patches are only for emergency, I've only used them once, and as soon as I get home I take them off and put on a proper patch.

When I get home I use rubber cement from an office-supply style jar of Elmer's rubber cement. I've had it for 4 years and it hasn't dried up. The little tubes, yeah, they dry up once opened. I do have some but I don't open them unless I must.
