Hey Jeff - This outfit seems to rent snowshoes for a reasonable price, their shop in Sonora is a quick jog of the 108:
Sierra Nevada Adventure Co.
173 S. Washington St.
8am to 6pm Daily
Alternatively, I've got a spare pare of MSR Denali Evo Acsents I could lend you if you can fetch them from downtown Oakland.
